I have a CZ 455 with 22lr, 22 mag, and 17hmr barrels. I have decided to chop the 22lr barrel to 16.5” and thread it. What length should I cut the 17 and 22 mag barrels for best velocity?
If that’s the case, just cut them all 17 or 18, and roll.....I don’t notice much difference in handling from 16-18”, with a 22 suppressor....over 18”, I can tell, but that’s just because anything longer than 24” total bugs me.....just a thing.
