I'm happy with it now. What is truly amazing was the rifle was still holding ~2" groups with the rear base loose. The front ring/base must have really been doinga great job.
Yep, FG, u no whut dey say - der'z nun like an old 'un.
Check your screws.
Had something else happen today that is a mystery to me even though this is the second time I've seen it happen (not on the same rifle). On that first shot (before the adjustment), my breechplug nearly unscrewed itself. It was about 2/3 of the way out. I've NO explanation for how that happens. Anyone else ever see that occur?
