What caliber? I shoot the 52 gr. FBHP from Speer in my 223 and 22-250. Hits like Thor's hammer. I prefer them in my 223 over 22-250. Slower FPS so they are easier on fur. Usually one hole, no exit. I would think the 55 would be good also. OAL for best accuracy is just off the lands a couple thousands. Test them out and let us know....
