Well, went to the range today and the new barrel shoots great! After getting close to center and verifying no keyholes at 50yds with 275 bloodlines, I moved to 100 and shot a few groups.
I only had 2 of the Barnes TEZ's left which were the worst shooting ones before, and both of them flew perfect and landed within an inch of each other. The bloodlines did ok with the biggest group at 3 1/2" with open sights at 100. Not one even close to keyholing. Pretty sure I can get better with some load development but overall I now have my accurate rifle back.
