I've been playing with subsonic, here are some of my disorganized thoughts.
They are MY THOUGHTS, not meant as "replies" to other posts. Not arguments.
-22LR subsonic is Da' BOMBE'!!! Quieter than a pellet rifle. And has adequate power for pest control. Too much for in town!
-Other 22's....Making an AR platform quiet is hard. And 223 NOT subsonic but suppressed is a complete waste of money IMO.
-A truly subsonic 22 on the AR platform will be a single-shot which kinda' defeats the purpose of the AR platform nehh???
-Making an AR quiet using the 30cal is much easier, and pretty cool, but useless. Too heavy for pests, too light for hunting.
-IF one chooses to try the big 22CF cases (22BR/221FB/22-250/223 etc) I agree with Trailboss as the only safe alternative.
-I've had really poor luck using cast lead bullets in rifle barrels.... I've still got one soaking and am concerned about ruining it.
-Big subsonic stuff kicks the everliving SNOT out of me. My current brake is 12" long and I'm working on tripling it's capacity.
