That's interesting. 300 Whisper, very cool. As far as the suppressor, love that too. But isn't it a huge rigamarole to even be allowed to posess one legally. Tax stamp, Extensive background check etc? Even if I went through all of that, the supressor still wouldn't be legal for hunting in MN. Any idea where I can find a ballistics table for the 300 Whisper. Is that strictly a handload? I've never heard of one before. Also, whats is the Mach 4 supposed to be like. Centerfire?, Rimfire?, If it's anything like the mach 2 or HMR, that's too small. I still need to be able to kill a coyote.
