[QUOTE="Bart B, post: 697272, member: 5302"] Kirby, please reread my post. I never said your loads do that. I said: [B]'Twould be nice to see some actual pressure measurements (CPU or PSI; whatever system one has) on Kirby's cartridges. I mention this as most cartridge brass starts extruding back into bolt face cutouts/holes at around 65,000 to 70,000 CUP.[/B]'Course if you think "most cartridge brass" includes yours, then so be it. I don't know if yours fits in this category or not. I've fired several hundred proof loads with peak pressure averaging 67,500 CUP. Some of it had raised areas above the normal surface matching bolt face cutouts. Others didn't. Also, if one goes from a starting charge weight to another that shows what the objective is that's met by changing charge weights, that's a load development. [/QUOTE]
