Definitely stock related now. Rear trigger guard bolt came loose over time, and that's 3-4 MOA vertical if it's tightened. Trouble is it wont stay tight. So that's out now as well. Will see. Doesn't seem to group as well with all the bolts out so thinking about dremmeling the inletting to see if that helps. With all the bolts in it single holes with ease at 25yds, but the hole keeps wandering as the bolts come loose. 50 shots is enough to see the rear loose, and the fore-end need a 1/4 turn again. And that's with them done up super tight.
