Anyone Loading for a GA Precision Crusader?

I know these guns have tight chambers, but last weekend I shot a few rounds of 178 Amax with 41.5 grains of imr4895 and got a lightly stuck bolt. I shoot 43.8 grains in a TC Venture with no pressure signs at all and same brass, primers etc. Just goes to show you every gun is different and to start low and work up. I figured 2.3 grains below my TC Venture's accuracy load would be plenty to back off, but I was wrong.

Anyone else seeing this kind of differences out of a GA precision chambered .308? I'm kinda scratching my head here.

Any good recipes for a tight chambered .308? I promise to start real low and work up to it...

I'm a dummy. Just rechecked and my TC venture load was with 150 Sierra's. At least Monday is about over.
