I mentioned using a 44 mag in OP because it is an ideal canidate for a suppressor. For best results subsonic speed is required (less than 1088 fps at 32 degree farenheight), and a heavy bullet will increase killing potential....sound like a 44 mag to me. Furthermore a bolt action or other locked breech will force gas thru suppressor creating best results.
This being said one could still suppress a semi auto or revolver if desired, results would be less effective. But to each his/her own.
I believe this will pass in some form or another...likely be a year or two before it happens in real life. I will post any new developments of this as I hear them.
Any body have an inside track on this topic?
