Some members in a separate thread described tuning their bolt action rifles for optimum accuracy by adjusting the torque on their actions screws. I've never tried this before. Some posted some large reductions in group sizes by lightening or tightening the torque on the action screws. How many have tried this enough to confirm that groups sizes will shrink or enlarge with different action/bedding screw torque on bolt action rifles? Care to share your approach and thoughts?
