Like a Moron I decided to remove the brake to try a new one I had made, low and behold the brake was on tighter than the barrel nut somehow and the barrel spun loose. So between sitting in my blind in the morning and before heading back out for an evening sit I drove over to another property of ours and rechecked her zero (after resetting headspace and getting the nut good and tight the other night). Off the hood of my truck I used the rangefinder and had the target at 145yds. After 2 shots to adjust her down and over a bit, I made a nice 3 shot group just under 2.5" and right to POA. Now to get some venison in the cross hairs.

FYI- the load I was shooting was 44.0gr of RL7 under a 300gr Hornady XTP with a firm crimp from a Lee FC Die.
