I picked up 500 of them from Graf's. They are noticeably shorter than the 62 gr HPBT bullets from Mid South. So they stabilized in my 1 in 12" twist Remington 26" barrel. 5 shot group was about 1.5" at 100 yards. The grouped around an inch from the 1 in 8" twist AR's. So, my thoughts are that they are a little less accurate than the HPBT's in the AR's, but useable in the bolt gun. Going to try them in my son's 20" 1 in 12" twist 22-250. If they shoot in that, they may turn out to be a good antelope bullet for Montana. If you ask me, it looks like a slightly overgrown version of Hornady's current 55 gr SP, with the mild boat tail. A decent bullet, given the bargain price.
