Terry Wieland worked with a couple of those for an article in Rifle 288, (Sept. 2016), one at the FTW Ranch, then another he bought for himself later. He reported good accuracy and consistency with both, using factory ammo, and perfect function as well. No break-in was involved with either, btw.
I'd replace the scope with one known to be reliable and try some other ammo. I have the very similar Hawkeye Predator in .308, and it shoots well with ammo it likes, though nary a single round of factory has ever gone down its pipe.
