So I have a beautiful No.1 30-06. It shot very good groups until I have a trigger job done. Trigger is crazy good now, but cant get gun to group well anymore went from .75" groups to 2.5", I still have shells that it was shooting great but now it wont group them and I've tried many other types and weights too. I wasn't able to shoot gun after trigger job for quite some time. Now the gunsmith that did it has moved off. My guess is when smith took the forearm off it caused some kind of problem with it grouping. I've read that No.1 can be very finicky on grouping due to the forearm. Any suggestions or things I can try? I've swapped scopes and checked all screws.
