Thread: Quietest firearm possible?

Yep I see there is a De Lisle reproduction on trademe at the moment, but they want $2000 for it.... I have a Baikal 7.62x39 and it shares the can on my .308, it is quiet with subsonic loads but not as quiet as some of the .22's i've handled, I think @Friwi must be right, my mate has a Marlin XT22 with a suppressor and it make less noise than an air rifle. Maybe i'll stick with the 7.62x39, I've been using 150 grain Sierra .311 Pro Hunters with 7 grains of Trail Boss, are cast bullets worth trying?
