i tried plenty of subs, standard, high, stinger etc etc.
its not ammo,
It shot well after changing scope and freeing the barrel. Then a day later it strings up again. Suddenly it shoots great again after 20 rounds.
I feel like there may be something weird happening where it for wathever reason needs warm up shots.
Its a mystery. try something else tomorrow. When it shoots it shoots well, got some really good groups today. Its something related to the rifle it seems. Or the aupressor. Iam taking that off for a while. it did shoot well with it on a day ago tho.
I did notice a bunch of grey greasy paste depositing on the crown and in the suppressor. Dont know if thats a concern
Try SK long range , that's what we're all shooting in our CZs it's good ammo across the board , apart from suppressor or something fouling or touching the barrel or loose mounting , I'd say it's thread in the barrel mate or crown . Just like everyone else
So frustrating isn't it mate . I've had similar
That could be waxed ammo , check if you have used it ? I stay away from it to be honest
make sure you use a scope with parallax set to your target distance, and not a centrefire 100m px scope, that and poor ring height/cheek weld will introduce error and inconsistency- maybe not to the level you are getting but if your going to put it through all these tests, its worth getting that bit sorted
When you get that vertical stringing, did you notice any difference in the report of the rifle?
