I have a T/C G2 Contender in 375 Whisper (action, barrel & suppressor bought through SSK). I'm shooting 300 SGK through it over PowerPistol. At avg. MV of 1050 fps, I'm getting a report (really a crack) like from a 22 LR.....maybe slightly less. Speed of sound is 1125 fps. This is my only suppressor; I've not been around them or used them before. Normal?
