I finally got to try my new CZ455 today. It was cold, and I couldnt get a good shooting position, but I got the scope sighted in at 56yards with RWS subsonic.
The difference in impact between these and HV rounds is way bigger than I'd thought, but I intend to use the subsonics in .22 and get a 17 hmr barrel for longer shots.
Pic shows the best group, but I'm sure they'll perform like this all day long from a bench - I was laying down in gravel Most other groups came very close, but I called a lot of flyers, screwing them up a bit.
This Group is 7,5mm or 0.3 inches center to center. The rifle has about 150 rounds shot through it by now. No bedding yet, but it'll come
