On some of the shooting shows ,when have cans ,some sound like wet farts ,some it's just the bolt/slide hitting,and some sound like over amped 22's . I know some shows may amp up gain or push it down ,but hard to tell at times on these shows when a 45 with a can sounds like low power 45 or a 223 sounds like your ears would still be ringing after several rounds how supressed the cans really are.
