I picked up a savage 12 LRP in 6.5 Creedmoor and headed out to the range with my cleaning rod, rod guide, solvent and three boxes of Hornady 140 gr A-max to break the barrel in per the instructions on the Savage website.
I was a little hesitant about the idea of running a patch with two drops of oil down the barrel after cleaning--right before my next shot but I did it.
Anyways, I ran through the prescribed 50 rounds. Clean after each round for ten rounds. Clean after each three round groups for 5 groups. clean after each 5 shot groups for 5 groups.
During that process I had stiff bolts on about 15 of the rounds. I popped three primers and about 6 of the cases had indents from the ejector on the head--two them were pretty deep.
Is it normal to deal with pressure signs from factory ammo during the break in period? I stopped pushing oil down the barrel because I was worried that the oil was
bringing up the pressure. That seemed to help a bit, although I still popped one primer after I stopped using the oil. The last ten rounds seemed good. No pressure signs, no stiff bolt, no carbon blowing past the primer.
Was this just a normal part of breaking in a barrel?
