Re: Best sub-sonic .22 ammo 4 hunting w/suppressor
That segmented one from cci is nice. It can be hard to find though. If you do find it, make sure you are getting the subsonic one... the packaging between the faster lighter ones and the subs looks pretty much the same.
If you are really worried about your rounds down range, ditch the suppressor and run the Colibri ammunition. Not as accurate though, and you will need to place a good shot.
Like south said, use the tree for a backstop.
