[QUOTE="su37, post: 268651, member: 5541"] That's with the same barrel lengths. I'll bet most AI rifles are pushing 70K plus to get the speeds they are getting. Ackley lovers, and I are one, love to boast about how close they can get to magnum speeds with 10 grains less powder. Not so, at least not at the same pressures of the magnum case. My first 280 RCBS started out as a 280 Rem then was punched to the RCBS version then I punched it out to 280 AI. 500 rounds down the tube for each version. It was a Marqaurt 26" btw. Shooting at the same pressures, I gained about 75 maybe a 100 fps over the 280 Rem. No big deal in my book. Outside of the lack of case stretching the improved versions are overrated. If I was building a long barrel long range rig my preference would be the 284 Win or 7 WSM I believe for the most part they get better ES than the 06 cases but then there is always an 06 cased rifle that will prove you to be a liar.
