GAB!!! That 42.5 grain load will crack your bolt lug!

Maybe, maybe not.  I think the fit of the locking lug into the recess has a bit to do with cracking bolts too.  Some only bear on one edge, like one I took out of a 13000 serial rifle that had a cracked receiver.  On the other hand, I've shot some loads out of my parkerized 92/96 that had to be near proof levels.  The lug fully bears on it, as does the guide rib.  Was it you who said your chamber was out of alignment?  Maybe it was someone on another forum.  That could have some effect on whether or not a lug cracks too.

On to other things, I have decided on my Camp Perry load.  29.5gr of SPP210, a Swiss made powder that burns about 4198 speed.  The 168gr Nosler match bullet is only going around 2250fps.  I shot a lot of loads before deciding on this one.   None of the loads with 40gr or more powder come close to this one accuracy-wise.  I think that has something to do with muzzle pressure.  I shot five yesterday, 3Xs within an inch, one 10, one 9 that I'll take the blame for.  About a 1.75" group with the just outside the 10 ring 9.  I was using a 6 oclock hold at 100yds, 3.3" high at 100 should be right on with a center hold at 200.  Which is right where the 1902 sight is set!  I'm ready as I'm going to get.
