My sons cz has suddenly gone from a 10mm grouping at 25m to something that resembles Jaque Kallis's run wheel after a good innings.
Point of aim has been checked on the scope by removing it and placing it on my Falcon and it is not the scope. We have tried changing from the ultratec's that he was previously using and the same happens with Air arms as well as accupell.
All shots have been taken from a stand, so we cant blame it on the moegoe behind the trigger.
After removing the silencer, the grouping is slightly better, but not back to what it was.
The gun has had about 3000 pellets put through it, and the hand book states that to maintain accuracy, the barrel needs to be cleaned regularly. Prevailing sentiment out there is to leave the barrel alone and not clean it.
If anyone has advise on what else can be done, it would be really appreciated. :bowdown
