[QUOTE="carlbobh, post: 1440884, member: 69675"] I'm using the 150gr Nosler Ballistic Tip with 60.9gr of RL22. 3207fps with a 4 fps dev. Under <.25". Gun is a Remington Model 30, Shlen Select Match #5 1-9 twist. 26" length. I fire form off the shelf Rem 150gr PSP, get ~2900 fps on it and under .5" groups. OAL is 3.330 and .127 off the lands. I think you have to treat these AI's like magnums and give them a little more room to get moving, give you better velocity and less pressure sensitivity. [/QUOTE]
