Well, I may be asking too much of the brass, I'm on my 3d reload after fire-forming. If I wish to get to the bolt to open easily, I cannot put more than 129 grains of H50BMG in the case using the 300 Lapua Scenar. I'm not even getting to 3000 fps. I've tried working the loads up to about 3200fps, but I've broken two extractors in the process and broken a few caseheads. I have backed down reluctantly.
I have some GS 295's I was hoping to start using, but this lackluster performance is putting the brakes on my enthusiasm.
Perhaps with my particular rifle, 2 loadings is all that can be expected.
