How does the .270 Gibbs compare with a .270 AI in terms of capacity/velocity, etc.?

270



P.O. Ackely mentioned the only cartridge he couldn't get an "improvement" from was the 270.......

if you are getting 3100 from a 130 from your regular 270 win, this article claims you should be getting 3341fps from your acklyized 270, how many of you guys wanna call bull$hit on that, thats faster than the fasted 270 weatherby mag load I have listed



I've chrono'ed two 270AI's on a couple of occasions (they weren't mine)--I didn't see much improvement.

I did meet a guy who 30 years ago loved necking up the 06 case--to 338, 8mm, and 35 calibers. Eventualy he started AI'ing them. He said in every instance he saw decent gains with heavier bullets, very little gain with lighter bullets. That's been my experience with my two 06AI's. But maybe the latest powders are changing that?

Regardless, I find 8% gain with a 270AI very suspect.......

My first post......
I have an .270 ackley with 25" douglass air gauged stainless barrel. What ive learned its all about powder selection like with any other caliber. nosler 140 accubond, imr 4831, fed 215, norma case gives me 3100 fps easily without pressure 10 ft from muzzle. Standard 270 fireform load was 2800 fps. I started out with some other slower powders and was disappointed with the performance.
