Minus the ackley shoulder angle35 Rem is one of the few cartridges that was designed from the beginning with Ackley Improvement built in.
Nonetheless, it cannot be Ackley Improved.Minus the ackley shoulder angle
Eggs ackley!Nonetheless, it cannot be Ackley Improved.
Why not? You may not get a big increase in performance but that shoulder angle can be made to 40 and body taper decreasedNonetheless, it cannot be Ackley Improved.
You won't get much of an increase in performance, if any. There is little body taper and not enough case diameter for a different shoulder angle to help. That's why it hasn't been done.Why not?

I agree it won’t produce much gain at all, but jgs or Manson will grind a reamer if one wants to chase it. It’s a 23 degree shoulder vs the typical 40 degree ackley. I’m sure someone has tried it, just like you probably haven’t seen a 6.5 prc improved 40 degree shoulder like this:You won't get much of an increase in performance, if any.

It's notable that a vintage cartridge, introduced 3 years after PO Ackley was born, would come so close to his spec.
This is my point. I am not arguing with you about Ackley. I'm pointing out an historical oddity.It's notable that a vintage cartridge, introduced 3 years after PO Ackley was born, would come so close to his spec.
Some of my best groups were during fire forming. 🤷🏻♂️That’s what happens, all of mine have shot very well fire-forming the brass.
I haven’t got my best fire forming but I’ve got plenty in the 0.2-0.3 range forming brass. AI that 223 for a real treat.Some of my best groups were during fire forming. 🤷🏻♂️
Well, I never shoot better than .2 so maybe that's my problem. LolI haven’t got my best fire forming but I’ve got plenty in the 0.2-0.3 range forming brass. AI that 223 for a real treat.
I’ve shot a gunsmith friend’s shooting the 85.5 hybrids that was slick and very long barrel life. A lot of performance before stepping up to the swift, -250 or creed that eats barrels.Well, I never shoot better than .2 so maybe that's my problem. Lol
I've thought about a 223AI running 77gr SMKs. That would be slick.
Two posts up from yers. #13. 😁👍How has the most famous "Ackley-ized" and greatest cartridge of all time not mentioned yet.
The 280 ACKLEY IMPROVED 🥰
You probably had that before 98% people knew what it was.Two posts up from yers. #13. 😁👍
And yes, one of my old favorites.
I think most people "still" don't know what it is. LolYou probably had that before 98% people knew what it was.
True, the nice thing is you can take a 270 or 30-06, rebarrel to 280ai, and get performance nipping at the heels of a 7rm with less powder.I think most people "still" don't know what it is. Lol

With a 26-28” barrel that would surpass a 22-24” 7rm. Next you’ll need a 7-300prc improved and really sling those big 7mm bullets.That's exactly how I got my first 280ai. I re-barreled a 30-06 Rem 700. I've been hooked ever since.
I built a 7mmPRC during covid. It does really sling em. 🤤With a 26-28” barrel that would surpass a 22-24” 7rm. Next you’ll need a 7-300prc improved and really sling those big 7mm bullets.
I still think they should have used the 300prc case for the 7, but I know why they didn’t. Simple fix with a call to jgs or MansonI built a 7mmPRC during covid. It does really sling em. 🤤
Rocks the shoulder pretty good too with the 180s @ 2950
Lol, I think they should have done like the 7PRCW.I still think they should have used the 300prc case for the 7, but I know why they didn’t. Simple fix with a call to jgs or Manson
Blame a lot of that on long range shooting. I remember in the late 90s early 2000s we’d get looked at like we were crazy shooting 800, 1000, 1200 yards and by the early teens a mile and 2500+. People wanted more horsepower than the rem mag or 280ai could provide to push those big, high BC bergers over 3000fps and you get the stw and rum and numerous wildcats, most impressive to me being the 7mm Allen mag. Now we’ve swung to long range precision out of a box and hornady has done an extraordinary job of marketing the creed and prc. I think they both can be improved upon and have that 6.5prc reamer with a 40 shoulder.I'm just afraid the 6.5 PRC, 6.8 western, 7PRC are going to be the final blow to really knock the 280ai out. It’s such a great cartridge & has such an interesting history with all its name changes and only being offered in the Remington semi auto rifle upon its initial release. It’s been fighting for the spotlight its whole life. Lol
Simple fix, you can have oneLol, I think they should have done like the 7PRCW.
Short action, 6.5 PRC case, necked up to 7mm.
Being left handed short action options are much more abundant.

AI were reserved for the wildcatters, the crazy guys who were going to blow themselves up. No one is pushing it like the “new cartridges” and I think it still has a cautious stigma.
Agreed, touching off a 338AM is quite fun. I’ve had 2 Kirby Allen rifles.to be fair, anything Kirby Allen comes up with is gonna be a hoot to shoot
I would probably just do a 7mm-08 AI if I ever get around to it finding a good gunsmith to ream my Tikka barrel.Simple fix, you can have one
Swift creek rifles, give gray a call.I would probably just do a 7mm-08 AI if I ever get around to it finding a good gunsmith to ream my Tikka barrel.
I use cow method for stuff like the Allen’s but that’s the beauty of the ackley, fire form with a load of the base cartridge. Its design allows for standard ammunition to be shot accurately. In my mind this was done just for those people who ask “what happens if you’re off on a trip and can’t buy any ammo in the store”.Match shooter buddy of mine used to fireform all his wildcat brass with bulk bullets and Bullseye powder @ ~10% of case capacity.
Doubt he got good groups that way tho . . . . and I'm not promoting this method . . . but he was a pretty accomplished shooter.
Who did you have ream that barrel? I have a Tikka TAC A1 in .260 rem that shoots lights out and I am thinking of rechambering to get that extra bit of oomph out of it...I get a solid 200fps gain in a 260ai over a standard 260 in a 26” barrel. All of my current rifles or builds are improved variations or ackley improved of the standard cartridges.
How many rounds have you got on it?Who did you have ream that barrel? I have a Tikka TAC A1 in .260 rem that shoots lights out and I am thinking of rechambering to get that extra bit of oomph out of it...
