I'm going to lay this out. If you live in a state that allows you to hunt with a suppressor, you will kick yourself in the rear for having waited to get one! POI shift is totally firearm dependent in my experience, some will move the point a little, some not at all, unless you have a faulty suppressor to begin with. It's worth having one, for me, because you don't light the whole woods afire every time you fire a round. They also may give you a very slight advantage hunting, but the bullet impact makes a loud smack when it impacts, so if you think your going to sit in one spot and clean out what hickory tree full of squirrels you'd be mistaken. When ol cousin Leroy gray's head pops, and sounds like a fast ball hitting the catchers mitt, and the next one you shoot sound the same way, they don't just line up on the limb and wait to be picked off, they run for the hills just like you'd fired that first shot gun blast, but it's a whole lot easier to hit them running with a shot gun than a 22LR! On HV rounds there's still the loud crack from the bullet, but the muzzle blast is masked and its much harder for the shooters location to be determined. On another note, you can't control when a semi auto cycles (unless you hold the bolt closed), but most bolt actions can be cycled very slowly and quietly if a follow up shoot is needed.
