After I had my CZ barrel cut to 17.5", CCI subs go supersonic on me. RWS does not. Most target ammo does not. The air temp was 21*F at the last test, giving a barrier at 1074.xx FPS. CCI says SSHP ammo is loaded at 1050 FPS, which I should not reach until 0*F.
Is CCI loaded hot?
I'm shooting a CZ 452 Varmint, regarded to have a tight bore; will bore size influence velocity?
