I'm looking at buying a CZ 452 American. I'd like to shoot sub-sonic ammo through it because it's easier on the ears.

My issue is.... I know the longer the barrel, the higher the velocity. That rifle has a 22.5" barrel, is sub-sonic ammo supposed to go through a certain barrel length? ie under 20-22" so it doesn't go over the 1,126 ft/s mark?

barrel length shouldn't be an issue
