without meaning to sound rude (for a change) Give it to a better shooter Sunday @ tondu
If they can shoot / Group better with it better than you, its not the gun that needs improving!
If it don't group it could be pellets / trigger.
Did that this week with a Mpr.
When your holding it, how steady are you? Can you hold it inside a 15mm kill at 55 yards?
Are you sure your range finding is right?
How about partnering me Sunday, I can check what your doing then as we shoot round?
