-New 30” McGowen 30 Nosler barrel on a near new Remington 700 action.
-Used Forester go/no-go gauges.
-Running Peterson brass, Ramshot Magnum powder, Hornady 225gr BTHP and using Ramshot load data.

With new brass I was getting a heavy bolt lift on a couple, but no other pressure signs and velocity around 2,850fps. Top of the charge had a heavy bolt lift on every shot.
Bumped the shoulder back .002 and loaded at the bottom charge weight. Same issue, but worse. The brass is showing rings around the top, middle and by the case head. Not separation, just scratching.
Any ideas?
