Thanks Johnly - would probably want to shoot 150's in it. I used to have a 10" bull and 12" Fox Ridge barrel - both had 1-10" twist, and both were amazingly accurate. With a max load of 296 and Sierra 150 spitzers, the 12" barrel clocked at 1550 FPS. Shot a bunch of 40's in IHMSA with it, and I am very sorry that I sold it. I am still a bit concerned with the 1-12" twist, but may take a chance with it.
