Thread: How to make my .22 quieter

CCI subs are rated at 1050 ps. Speed of sound varies but generally is 1100 fps at sea level with atsmosperic pressure around a standard reading.

Seem to be reading more an more about a few rounds in a box of subs going "crack". I've never experienced it with my CCI subs which are all really old stock.

It would seem unusual for every round of yours to break the sound barrier. The suppressor of course cannot get rid of that crack, only the sound of the powder going off.

Something else is amiss. Have you tried a different brand of subs? Is your rifle stock standard, ie factory barrel length. What is your rifle?

With my Marlin SA the loudest sound is the action cycling.
