Whether it makes a difference or not, there is no denying that the 7PRC and 7RM offer more performance than the 270 (physics). Whether it matters or not, depends on the game. That's why the 7RM was developed. Flatter trajectory than the 30-06 was needed, but the 270 was believed marginal for elk. And for educational reading, there is a 270AI. MANY 270 shooters are spending a lot of money trying to make their 270 the equal of the 280AI. 270AI educational reading assignmentBut unfortunately they never can, due to the larger bore of the 7mm, the small advantage in capacity of the 280 case, and the better high BC 7mm bullets. Have fun researching the rifles you'll never own So you feel that ballistics tables kill game. Aren't you special. Bet you need a bench and a bi-pod as well. Didn't do your homework either, little one. (Reading for content is a skill, too.) P.O. Ackley ( the "A" in AI.) P.O. ACKLEY FIREFORM IMPROVED WILDCATS FROM CURRENT FACTORY CARTRIDGES Cartridge - Performance Gain over Factory - Ackley Comment 270 Win. Ack. Imp. - Little or none with more powder - Not recommended, factory 270 is better Should have stayed in school, little one. 8>) GR I've got the book. 1962 copyright. I know you're living in 1925, but powders and bullets are far different than in 1962. Is there, or is there not, a .280 A.I... but no .270 A.I.? P.O. ACKLEY explained it to you, you just weren't paying attention. (again, reading for content is a skill) How many factory rifles are chambered in .280 AI as opposed to the .270Win? How many are sold? How about ammo manufactures/offerings/cost? Wait for your 7mm snow-globe to settle. As for modern power and bullets? The ones here, and on their way, will make the .270Win shine even brighter. That's what terrifies you. Say a 165 gr. ABLR, BC=0.62/SD=0.307, on top of a full charge of RL-26 for ~ 2,900 fps MV...? ...if ballistic tables killed game. 8>) GR

But, at a buck/round just for the ABLR bullet...?
Can most likely get close enough not to need it.
When Speer makes a 165 gr. high BC Hot-Cor bullet... will be the time to really get interested.

Still waiting for answers . . . What other factory 270 fast-twist rifles are available? What 270 loaded ammo with a high BC (>600) is available? As for modern power and bullets?
The ones here, and on their way, will make the .270Win shine even brighter.
That's what terrifies you.
Say a 165 gr. ABLR, BC=0.62/SD=0.307, on top of a full charge of RL-26 for ~ 2,900 fps MV...?
GR Not too terrified. I get 3030+ from my 24" 280AI with RL26 and a 162ELDX 631BC Bullets less than .50/ea.

SD, however, is a good indicator of penetration, which, among other things, does kill game. 162ELDX 631BC: SD=0.287 For a .277" bullet, that SD would be ~ 10 gr. less bullet weight. ie: ABLR .277/150 gr. BC=0.591 SD=0.279 MV~3075/24" Bbl. When you can't find your inexpensive HDY ELDX bullets? ... it will be b/c they shifted production to their new, high BC .277" bullet. ... if ballistic tables killed game. 8>) GR

It's a valid question to ask, how much high bc factory ammunition is or will be available to take advantage of the faster twist or will those who buy these continue purchasing "normal" .270 cartridges and see no advantage at all? They might as well buy a Ruger American. That's one of the advantages of the CM's and PRC's, they were designed from the first for appropriate long-range bullets. I rather like the idea of the rifle, but question the real utility of it in .270.
Of course Browning's intent is to sell rifles regardless of utility and I am OK with that.

Of course Browning's intent is to sell rifles regardless of utility and I am OK with that. That is the issue. Will ammo manufacturers jump on the bandwagon with ammo that won't shoot well in most 270 rifles on the market, and then weather the nasty reviews and phone calls? Or will gun manufacturers jump in, producing fast-twist 270 rifles, when there aren't enough long range 270 ammo offerings to justify them, or shooters to buy them? Browning did, but will others follow suit, or just focus on the 7mm PRC? I know if I was buying that particular rifle to focus on long range hunting it would be a 7PRC, without question.

162ELDX 631BC: SD=0.287
For a .277" bullet, that SD would be ~ 10 gr. less bullet weight.
ie: ABLR .277/150 gr. BC=0.591 SD=0.279 MV~3075/24" Bbl.
GR Interesting, but Nosler shows the MAX load of the fastest powder for that bullet topping out at 2918 I can run the 7mm 175 ELDX Hornady near that speed in the 280AI. BC 689 SD 310 Clearly a better elk load. And a 7PRC can run it over 3K.

Think the elk will notice? 8>) Till HDY comes out w/ one: Sierra Tipped GameKing: .277"/175 gr./BC=0.560/SD=0.326. (P.S. Nosler's loading tables aren't the only ones out there) And that 175 gr. 7PRC at 3,000 fps? ~ 30 ft-lbs of recoil from an 8.5 lb rifle. Good luck w/ that from field positions. To 400 yards, the .270Win/150 gr. is all a rifleman really needs. A higher twist/BC bullet - will make hitting at that range in less than optimal conditions easier. A higher SD bullet - will increase penetration if needed. That's all. Takes away any real advantage the 7mm's had. And being the new Std. Military caliber... believe that a lot of R&D will go into state-of-the-art .277" projectiles. The Future is now. GR

GR How is the 6.8 Western doing? Other than BACO, hardly any rifles chambered for it. Other than BACO, no other ammo manufactured for it. Here's an article on your wet-dream savior: Guns and Ammo 277 FuryI found this to be particularly salient: Will there be additional cartridges planned for a “Fury family?” A representative with SIG Sauer told me, “Yes.” There is no timeline yet, and that person wouldn’t say what was next in line. I’ll step out on a limb and predict that the next one will be a 6.5mm SIG Fury, and I’ll bet that it will be more popular than the .277 SIG Fury proves to be! The .277 SIG Fury arrived to us first because it is simply a commercialization of what SIG Sauer has already been developing for the U.S. Army’s NGSW requirements. The civilian market wants rounds in 6.5mm, 7mm and .30-caliber. That’s why I’d be willing to bet that a 6.5mm SIG Fury is next up. Like the .277, it would push a 140-grain bullet at 2,970 fps from a 16-inch barrel. A 24-inch barrel would send it downrange around 3,100 fps.Good to see that a 24" 6.5 Fury would only be about 100fps slower than a 140 in the 280AI

Will either be grim... or extremely loud. Either of which will produce Minute-of-Basketball precision from the neophyte, or even average shooter. Look forward to the booming used market in the latter stages of your Good-ole-Days. 8>) GR
