Since it uses a larger diameter case derived from the .375 H&H, the 7mm Magnum has a very large powder capacity and is capable of shooting the same weight bullet faster than the .30-06. On the other hand, the .280 Remington is normally offered with 139 grain, 140 grain, or 150 grain bullets, but it’s possible to find a few loads with 156 grain, 160 grain, and 165 grain bullets as well. Since it uses a much larger case diameter, most rifle magazines will hold more .270 Winchester, .280 Remington, or .280 AI cartridges than 7mm Remington Magnum cartridges. If you’re interested in doing so, it’s also possible for a skilled gunsmith to convert a rifle in .280 Remington over to the .280 Ackley Improved chambering with a chamber reamer. It didn’t take very long before the .270 Winchester was firmly entrenched as one of the most popular hunting cartridges used in the United States. Remington tried to match Winchester’s 270 Win. As you can see, that particular 7mm Mag load has a little more free recoil energy than the .280 AI when used in the same weight rifle, but is shooting the same bullet only 50 feet per second faster. Your articles are not like that. Instead of using the much more commonly used .284″/7mm bullets like the 7mm Mauser (and many newer cartridges like the 7mm-08), for reasons that aren’t clear today, the .270 Winchester used .277″ bullets. Not only is it a belted magnum cartridge, but it has a larger rim diameter and a 25 degree shoulder. They got lucky with the 7mm Rem mag. In 1995 I bought a Model 700 Mountain Rifle chambered in .280 Remington. Those bullets are much more resistant to wind drift and retain much more energy as they travel down range. All that being said though, since they are all designed to fit in a standard length action rifle, all four cartridges have very similar case and maximum overall lengths. Based on its .284-inch bullets and ballistic potential, the 280 Remington should have been an overnight success. The Lyman 50th Edition (p197-198, 212-216), Speer Number 10 (p182-184, 193-196, 201-204), and Hornady 10th Edition (p351-355, 391-400, 406-411) reloading manuals were used as references for the history of the cartridges. Later, they also offered it in their Model 742 autoloader and Model 760 slide action before finally offering it in the Model 721 and 725 bolt-action rifles. In addition to all being excellent excellent choices for deer sized game, these cartridges are also suitable for bigger creatures under the right circumstances. While the .270 had a very fast muzzle velocity compared to other popular cartridges of the day, it was not an instant commercial success. Since they can hold more powder, Ackley Improved cartridges are capable of higher velocities than their parent cartridge when loaded with the same weight bullet. Also developed by necking down a .30-06 case, the .280 Remington offered hunters a slight ballistic edge over the .270 Winchester and also utilized the more popular .284″ bullets. It wouldn't even fit in the chamber. Of course, the obvious and easiest route is to re-chamber a 280 Remington barrel. During many of those critical early years, the cartridge was only available in the Model 742 autoloader. 11 Best Muzzleloaders For Hunters In 2020, Use A Thermacell To Stop Bug Bites While Hunting & Camping, 6.5 Creedmoor vs 243 Winchester Review & Comparison, 6.5 Creedmoor vs 7mm-08 Remington Review & Comparison, 6.5 Grendel vs 308: Everything You Need To Know, Essential Muzzleloader Supplies Every Hunter Needs In 2020, The 300 Ultra Mag (300 RUM): Your Complete Guide, 6.8 SPC vs 6.5 Grendel: What You Need To Know, 6.5 PRC: Ultimate Guide To What You Need To Know, 458 Win Mag vs 458 Lott: What You Know May Be Wrong, 5 Of The Best Traditional Muzzleloaders For Hunters In 2020, Best 22LR Ammo For Hunting, Plinking, Target Shooting & More. Some were reluctant to adopt the cartridge, but many American hunters eventually came to appreciate the flat shooting characteristics of the round as well as the fact that it was so effective on thin skinned game. The introduction of the massively successful 7mm Remington Magnum in 1962 also derailed any prospects of the .280 Remington catching on to any large degree with the general hunting public. Take your pick. The answer is that one fits in to a short action and the other gives you about an extra 100 to 150 FPS±. Additionally, those smaller diameter .284″ bullets used by the 7mm Rem Mag have a higher ballistic coefficient and more sectional density than .30 caliber bullets of the same weight used by the .30-06 Springfield. You can’t beat the .270 Winchester or the .280 Remington. Some gun designers necked up the .30-06 to develop bigger cartridges like the 338-06 and the .35 Whelen. Latest. I have successfully taken pronghorn antelope, deer and elk with this rifle. It is true that certain factory loads and handloads for the .280 AI can come very close and even exceed the performance of typical 7mm Remington Magnum factory loads. Maximum pressure obtained from SAAMI (p23 and 28). If your a fan of heavier bullets the edge goes to the 280 rem. Like has been stated, you can buy .270 ammo anywhere that sells ammo, where as the .260 is not nearly as common. For this reason, the .280 AI is best suited for handloading. However, the larger .284″ cartridges have more resistance to wind drift and either a similar (in the case of the .280 Rem) or flatter trajectory. With a completely different lineage than the other three cartridges, the 7mm Remington Magnum has a unique look as well. Mule Deer Cartridge Showdown: .270 Win. With the ballistic benefits of the 7mm bullet, and case capacity allowing almost identical stats to the .280 Rem, the 7×64 is a convenient stopgap between calibres based on the .308 Win and the heavier recoiling magnums. The unique roots of the 7mm Remington Magnum and the shared heritage of the .270 Winchester, .280 Remington, and the .280 Ackley Improved are all obvious in the photo below. It shoots flatter than the .30-06, so is probably an ideal compromise between the two, at least on game up to elk in size. The same goes for the 145gr .270 Winchester vs the 150gr .280 Remington load. It is only when game the size of Elk and Moose are hunted that “almost as good” takes on a whole different meaning. The .270 Winchester uses .277″ bullets while the .280 Remington, .280 Ackley Improved, and 7mm Remington Magnum all use slightly larger .284″ bullets. That might not seem like much, but the .280 Ackley Improved (also known as the 280 AI, 280 Remington Ackley Improved, or 280 Rem. By 2000, much of the popularity of the .280 Remington had once again waned. Here’s one last thing to consider when comparing these cartridges: magazine capacity. [Re: yotekyllr] White Eagle Die Hard Member III Registered: 02/26/02 Posts: 2878 Loc: The Dark Side 280 will better either the 270 or the 30-06 a fine round almost perfect if there is such a thing However, even though the cartridge closely approaches the overall performance of the 7mm Remington Magnum, the .280 AI still has somewhat less recoil since it requires less powder to achieve a similar level of performance. All things considered, the .280 Remington had a lot of potential and should have been a big success, but the company made a couple of major blunders when they rolled out the new cartridge. The table below compares the recoil produced by the Nosler loads compared above for those cartridges when fired from a 7.5 pound rifle. Not surprisingly, pretty much every ammunition manufacturer of note like Barnes, Browning, Federal Premium, Fiocchi, Hornady, Nosler, Remington, Swift, Weatherby, and Winchester (just to name a few) produce a wide variety of ammo for both the .270 Win and the 7mm Rem Mag. Are you looking for a great cartridge for sheep, mountain goat, or tahr hunting where you need a heavy hitting cartridge with manageable recoil in a lightweight and easy to carry rifle? If not, then you should probably stay away from the .280 Ackley Improved (unless you’re fine with just 1-2 brands as factory ammo options) and go with either the .270 or the 7mm Mag. This is because it takes an additional 3.5 grains of powder to produce that additional 50fps of velocity. Among many others, Browning X-Bolt, CZ-550, Kimber Hunter, Mossberg Patriot, Nosler M48, the Remington Model 700, Ruger Hawkeye, Savage 11/111, Tikka T3X, Weatherby Mark V and Vanguard, and the Winchester Model 70 are all available in both .270 Winchester and 7mm Remington Magnum. I used Nosler’s own reloading data published online (available here, here, here, and here). That being said with proper bullets, and I tend towards the 150 grain in .270 though I’ve had good results with the 130’s. Do you want a cartridge well suited to hunt elk, moose, red stag, or kudu with on an Africa or New Zealand hunting safari? Ackley Improved 40 degrees) hit something of a sweet spot between the .280 Remington and the 7mm Remington Magnum. Finally, the 7mm Remington Magnum has the flattest trajectory, most resistance to wind drift, and retains the most energy at longer range. Reactions: Gb300wm, DHuffman and Mulligan. Even so, the 7mm Remington Magnum can hold significantly more powder than the other three, which is due in large part to its larger diameter case. All of them will kill deer with equal efficiency. Among other things, he’s particularly well known for his series of “Ackley Improved” cartridges. That also becomes an issue if you need to travel and can't bring live ammo, as you will need to buy it there. Can the .280 AI really live up to the claim made by some that it can do everything the 7mm Mag can do, but with less recoil? Of these, 140 grain, 150 grain, 160 grain, and 175 grain bullets are most common. Even with a few name changes, this cartridge is still one of the best around. Reproduction in whole or in part without permission is prohibited. Case capacities and reloading data were obtained from Nosler (here, here, here, and here). The only ammo you can buy for it will be labeled 280 Remington unless it's old stock. First, the .270, .280, and .280 AI are all very similar in appearance: they have the same rim diameter as well as very similar case lengths.

Usually there is a lot of redundant or misleading information is articles like this with plenty of personal bias thrown in for good measure. This undoubtedly has an impact on bullet velocities. This prevents .280 Remington ammunition from being chambered and fired in a .270 Winchester chamber. This means I will earn a small commission (at no extra cost to you) if you make a purchase. This comes at the expense of more recoil though. However, there are some important differences that set them apart from each other. The results are also about what you’d expect for the Hornady Precision hunter loads for those three cartridges. Most hunters and shooters in North America are probably familiar with the venerable .270 Winchester and 7mm Remington Magnum cartridges. From Guns and Gear® Season 4, Tom Gresham discusses the .280 Remington. In other words, that extra powder is resulting in diminishing returns in terms of velocity, but still producing more recoil. Using 140 gr bullets in the 270win and the 280 rem there's not a nickel's worth of difference. 270 vs 308 WIN: WHICH ONE SHOULD YOU HUNT WITH? In the heavier bullets (150 grains and above) of similar design the .280 Remington has a slight edge in muzzle energy. Buy an excellent 7mm Remington Magnum hunting rifle here. Does the perfect muley cartridge really exist? So, if it wasn’t bad enough that the management at Remington didn’t fully get behind the cartridge and offer it in a bolt-action rifle from the start, they also kept changing its name. This is an area where the .280 AI really shines because it has a similar or slightly superior trajectory and resistance to wind drift when compared to the 7mm Remington Magnum, but less recoil in a lightweight mountain rifle that’s easy to carry in rough country. Yes you can use the .280 in that action. The recoil energy and recoil velocity figures are taken from various sources including the recoil nomograph in the Handloader's Digest 8th Edition, various online recoil calculators, the Remington Shoot! I used the Hornady Ballistic calculator and ShootersCalculator.com to compare trajectory, wind drift, and recoil for the cartridges. The .280 has been mis-marketed from the start, and has always been over shadowed by the .270 Win on one side and the 7mm Rem mag on the other. However the ballistic coefficient of equal weight bullets favors .270 caliber bullets over 7mm (.284) bullets of similar design. April 9, 2018. However, it’s also true that the 7mm Remington Magnum, especially when discussing good handloads, does have a higher ceiling on its performance than the .280 Ackley Improved. Go with the .270 Winchester if you want the cheapest or easiest to find factory ammo or if you’re sensitive to recoil. This was due to a number of reasons, one of which was the fact that the .270 Winchester fired unusual size bullets. They eventually chose the bolt action 1903 Springfield rifle chambered in the new .30-06 Springfield cartridge. Furthermore, shot placement and bullet construction / weight is far more important than choice of caliber. However, the brass is then fireformed to .280 AI after doing so, which is yet another reason why it’s a good idea to handload if you like the .280 AI. I think most shooters would agree that the 6.5 Creedmoor is a fantastic cartridge for competition shooting. For the vast majority of hunters, there is very little difference in their performance at typical hunting ranges (inside 300 yds). With all that in mind, it’s easy to see why lots of hunters and shooters in North America quickly got behind the flat shooting and hard hitting 7mm Rem Mag. Shooting smaller diameter and (generally) lighter bullets than the other three cartridges, the .270 Winchester has a very flat (though not the flattest) trajectory and the least recoil of the bunch, but also carries the least energy downrange and is the most vulnerable to wind drift. A Bonnier Corporation Company. For that reason, the 25-06 vs 6.5 Cree… In this case, it takes about 6% more powder to produce about 1.5% more velocity and this results in about 6-7% more recoil. Get a good hunting rifle chambered in the cartridge that you think fits your needs the best, learn to shoot it well, use quality bullets, and you’ll be all set for most hunting situations. Though only a few cartridges (like the 270 WSM, .270 Weatherby, and 6.8 Remington SPC) use .277″ bullets, the fact that the .270 itself is so popular means there’s also a decent amount of quality bullets to choose from for that cartridge as well. One area where the 280AI and .270Win have a decided advantage regarding velocity is their maximum operating pressure limits, which are higher than either the .280Rem or 7RemMag. Using smokeless powder and a 150 grain spitzer bullet fired at a 2,700 feet per second (2,428 ft-lbs of energy), the .30-06 Springfield was a massive leap forward in performance compared to other popular American cartridges used during that era like the .45-70 Government. Which is better? Considering that the 7RemMag came from the same .458, .338, and .264 Magnum (belted) case, when loaded to the same pressure levels and housed in a rifle of 26″, it will exceed any max velocity possible with the .280AI by at least 150fps (hand loaders’ have proven this fact for decades). Ackley, was very well known for developing wildcat cartridges in the latter half of the 20th Century. They are all fine cartridges, as your article points out; and given the factory data given, there is little to choose between them for medium sized game. #938051 - 03/19/08 07:58 PM Re: .280 Rem vs .308 Win ? It’s also easy to see why the 7mm Remington Magnum quickly pushed the .280 Remington even further out of the limelight at first. The actual performance difference between Ackley Improved cartridges and their parents varies, with some realizing a much bigger jump in velocity than others. While the .280AI is an efficient cartridge; however, it’s not “magic”. So in 1981 they changed the name back to the 280 Remington. And to top it all off, while a few older cartridges like the .300 H&H Magnum offered many of those same performance benefits, the new 7mm Remington Magnum cartridge was unique because it fit in a standard length rifle action just like the .30-06 and similar cartridges like the .270, .280, etc. For those reasons, most 7mm Remington Magnum loads have more energy remaining downrange, a flatter trajectory, and (all other things being equal) will penetrate better than .30-06 Springfield loads using the same weight bullets. 130 grain and 150 grain bullets are by far the most common. E tips so its ready for CA hunting. It’s also better suited to using heavier bullets than the other cartridges. While there is a large amount of overlap in their capabilities, each one does offer certain advantages. As you can see, the .280 Remington and .270 Winchester are identical up to the shoulder and have the same 17.5 degree shoulder angle, but the shoulder of the .280 Remington is moved slightly forward. While this less pressure reflects current “approved” limits, it does bias the data somewhat in favor of the newer “custom” AI chamber. I have killed and been around a pile of animals killed with .270s and .280s as wet have a few in the family. But such was not the case. The three .284″/7mm 140gr Nosler loads all use the exact same AccuBond bullet, just fired at different velocities: the 7mm Rem Mag is 50fps faster than the .280 AI, which is in turn about 150fps faster than the .280 Rem. I have a custom .280 Remington. It's a very capable round. The .280 is one of my ole favorites. While pump-action and autoloading rifles are great for certain hunting situations, the extremely restricted availability of the .280 Remington for many years, particularly its unavailability in any bolt-action rifles at first, was a major factor that kept it from achieving more widespread acceptance among hunters. The .270 Winchester has by far the least recoil of the bunch. With that in mind, the minor differences in trajectory and retained energy between the three are not at all surprising. That being said, the .280 Remington, .280 AI, and 7mm Rem Mag are generally a little better suited for hunting bigger game. Field & Stream may receive financial compensation for products purchased through this site. Additionally, the .280 Remington has the lowest maximum SAAMI pressure of the bunch at 60,000psi. The 280 Remington (case length 2.525 OL 3.330) and 270 Winchester (case length 2.540, OL 3.340) are basically the same, with the exception that the .280 shoulder is moved forward about 0.10 inch. The shoulder of the .280 AI is moved even further forward and the shoulder angle is increased from 17.5 degrees to 40 degrees. Indeed, depending on the exact barrel length of the rifles in question, the real world advantage one cartridge may have over the other may narrow considerably, disappear, or even flip in favor of the other cartridge. The chart below compares how much a 10 mile per hour crosswind impacts those same .270 Winchester, .280 Remington, .280 AI, and 7mm Remington Magnum loads out to 500 yards.As you can see, even though they have a very similar trajectory with both light and heavy for caliber bullets, the .280 Remington has a clear advantage over the .270 Winchester in terms of wind drift. What do the .280 Remington and .280 AI have to offer hunters, particularly compared to the .270 Winchester and 7mm Rem Mag? Do you primarily hunt medium sized game like deer, feral hogs, or black bear at ranges within 200 yards? By David E. Petzal. Of the two, the .280 Ackley Improved has a little less recoil, but ammo is easier to find for the 7mm Mag. Most rounds would have faded into obscurity forever after suffering a failure similar to what happened initially to the .280 Remington. However, the reduced body taper and sharper shoulder can sometimes cause feeding issues with certain rifles. Thanks for your support. Not only does the .280 AI offer a noticeable ballistic advantage over the .280 Remington, but it’s also capable of performance nearly on par with the 7mm Remington Magnum. This very likely hampered adoption of the cartridge to a certain degree. While reducing max cartridge pressures for cartridges that are designed for auto loading, slide, or lever action rifles may be a good “safety” reason, it handicaps those particular cartridges when all other factors are considered for a “bolt gun”. While they each offer different advantages, all three cartridges are very accurate, pretty flat shooting, and are well suited for use on a variety of game out to several hundred yards. Why not? The Nosler used a 24″ barrel for the .270 Winchester and 7mm Remington Magnum, but a 26″ barrel for the .280 Remington and .280 Ackley Improved in their published reloading data I used above. This is one of the most interesting points of comparison between the 7mm Rem Mag and .280 AI though. If you’d like to learn how the .270 Winchester compares to its parent case in the .30-06, read the article below: 270 vs 30-06 Debate Settled Once And For All. Both of those cartridges are very capable performers, though neither is as well known or as widely used as the .270 Winchester or 7mm Remington Magnum. For example, when using the same weight bullet, .280 Ackley Improved factory ammunition typically shoots 50-150 (usually around 100 fps faster) than most .280 Remington factory ammo. Remington made an attempt at knocking the .270 Winchester off its perch when they rolled out the .280 Remington cartridge in 1957. All will certainly work to one degree or another. Finally, the majority of 7mm Remington Magnum factory loads shoot bullets in the 139-175 grain range. Any modern, strong bolt-action that can handle a 30-06, 270 Win., 25-06 Rem. This is why the management at Nosler decided to standardize the .280 Ackley Improve and submit it to the Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) for approval, which it received in 2008. The .280 Remington is somewhat less common, but still pretty easy to find with Barnes, Federal, Hornady, Nosler, Remington, and Winchester all producing good quality .280 Remington hunting factory ammo. This helps support the blog and allows me to continue to create free content that’s useful to hunters like yourself. Yet it has never been and probably never will be anywhere close to as popular as either…nor is it anywhere near as popular as the 7mm Remington Magnum. At the 1,000-yard mark, we see around 26 inches less bullet drop, on average, for the .270 Win when compared to the 7mm-08 Remington. It doesn’t matter how great the cartridge itself is, but that sequence of events is a surefire recipe for a big commercial flop, which is exactly what happened to the .280 Remington. The 7mm Rem Mag load above still has about 3% more free recoil energy than the faster .280 AI load. The .280 Remington shoots about as flat as the .270 Winchester. Are you sensitive to recoil? The relatively new .280 AI is nowhere near as common as the other two and at this point, only Nosler and Hornady make .280 Ackley Improved factory ammo. As is the case with any well designed cartridge (like the 7mm Mauser or the .30-30 Winchester), wildcatters also quickly started modifying the .30-06 Springfield to accomplish a variety of different tasks. 7mm-08, 280, 7mm WBY, 7mm rem mag, 7mm ultra mag, all shoot .284 cal bullets. So, Remington renamed the cartridge AGAIN after a few years and went back to the .280 Remington, which is what it’s called today. Regardless of the cartridge you choose, you’ll have a gigantic bullet selection consisting of virtually every major style of bullet to choose from like the Barnes TTSX, Berger VLD, the Hornady ELD-X, GMX, InterBond, InterLock, and SST, the Nosler AccuBond, AccuBond Long Range, Ballistic Tip, E-Tip, and Partition, the Remington Core Lokt, the Swift Scirocco and A-Frame, and the Winchester Power Point (just to name a few). While I consider the 280AI to be a very good cartridge that will gain typically 100-125 fps over the standard 280 Remington it's NOT an equal of the various 7mm Mags.
