I have had to send my weatherby off to Mike at Brock and Norris and heard back from him today that the rifle is sorted.
Cut a long story short, I bought it off Ross on here, but it wasn't screw cut, so I did some research and found someone to do it. Since the screw cut was done, the rifle has been a pig, I started to fail my dsc1 shooting assessment and tbh was a bit embarrassed on the day (thankfully this was resolved with the estate rifle).
Mike has basically sorted the trigger, but has also recrowned the barrel as this was never done and in fact the screw cutting had seriously affected the accuracy of the rifle, meaning it would never fire true in its previous state.
Is the gunsmith at fault here? Should the recrown be done at the same time as the screw cutting?
I would like to thank Mike for doing the work properly and I can't wait to test and zero on Wednesday. I have a target from my last zero attempt and I'll show a comparison after Wednesday.
