I don't believe the 270 win in that letter is legit, it claims a 8.8% and a 7.8% gain, I guess I will assume the 8.8% was likely with 150 grain bullets,
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.......
