Thread: Cause of split groups?

Thanks for the all the input fellas very helpful, I've made a bit of a list easiest and cheapest first and started with pulling the stock off - first thing I noticed was the action screws were snug but not as tight as I'd think it should be, second thing was the thread insert for the front stud was 3/4 of the way out the hole, it looks like it was never inserted properly from factory, I'm thinking that could have caused some shift in bipod positioning. Cleaned and reinstalled the thread insert, and torqued the action screws. I noticed the positioning of the rear screw is now centred whereas before I took it apart it was hard to one side. Hoping one of those two fixes it if not I'll move down the list.

Scope is good although I can't comment on it's performance beyond the range yet, got one animal with it but in hardly testing conditions. Waiting to get this rifle sorted before I head out to glass some slips. It's a difficult scope to find reviews for, one of the only in-depth reviews I could find was in a magazine, I'll PM it to you

good man- I really expected mechanical not you - if you took anything away from all the info then slowly eliminate all possible - and carefully work thru them - I dont doubt this is actually simple as Tikkas normally shoot -
