Fisherman66, it is very easy to get rid of the sonic boom, just use subsonic ammo. Handloading makes it a snap. Just need a faster twist to stablize the heavier bullets. The sonic boom does not bother me when shooting my ar-15 suppresssed as long as I am not under a roof.
You do not need to win the lottery to suppress. My silencers just cost $20-30 plus tax. Of course the lathe and other tools set me back about $2000. Making a few cans put me in the black though.
