this seems like a good place to talk about "the noise"...
having a compensator on the end of the barrel DOES NOT NECESSARILY MAKE THE GUN LOUDER... if the barrel is shorter, the length of the comp, or more, it can be noticeably louder, but not really much more than the shorter barrel in the 1st place, if designed poorly the sound can be directed towards the shooter making it seem louder... how the ports are angled makes a huge difference... I have a retired tool & die buddy that has made me several, & by angling the ports away from the shooter, the shooter is not exposed to extra noise...
my 2 B.O.S.S.'s are on belted magnums ( 338 win mag, & 375 H&H ) & I don't notice much more noise than I'd expect from a belted magnum, but both are long barrels already... I have hunted with both... & yes it's painful, but IMO, not much more so than the same calibers / barrel lengths with out one
that said, IMO, silencers that reduce the noise enough to prevent hearing loss, aught to be legal to use when hunting... they can be designed to be quiet enough to help prevent hearing loss, while still being loud enough to discourage poaching ( which is likely the resistance to allowing their use )
