[QUOTE="tankgijohn72, post: 1486194, member: 77441"] Agreed, give that a shot. I think it is unlikely that you are hitting the rifling, but testing in this manner will prove it one way or another. If you aren't getting heavy bolt lifts then you aren't at a really high pressure. The main issue with the belted magnums is the headspacing. The rifle could headspace perfectly with a go/nogo gauge on a belted magnum gauge and the boltface to shoulder measurement be slightly short (take a look at the pic for headspace gauge. Its a forster, that's what I used rebarreling my win mags multiple times. It only checks boltface to belt and nothing else.) Using the marker method you can eventually determine where the interference is coming from whether it be the belt, shoulder, neck, bullet/lands. [/QUOTE]
