[QUOTE="geocodyrgia, post: 2732539, member: 98212"] I salt bath anneal at 950* for about 6-8 seconds (whatever time it takes me to drop another case in the other hole and then come back to pick the first one out at a slow/steady pace). I've pushed about 1200 rounds of 6mm Creedmoor with loads running 2900-3200 fps on the same 100 cases of Hornady brass and not a single split neck yet. I was annealing some 7 SAUM in the smaller case holder (the kit came with a double hole stand that will handle up to 308 and a single hole stand that handles up to 50 BMG) and the case (Bartram) got stuck for about 30 seconds or so when it expanded from the heat. Had color change to the head of the case so knew it was trash but used it to set up dies and mock up loads. The shell holder broke the rim off of that piece of brass when I tried to run it through my sizing die. I don't know all the fancy grain size hooey, but I could sure tell the difference between that one and one that didn't get stuck. Is an AMP better? Probably. Do I have the money to test it and would I ever be able to shoot the difference? I doubt it. [/QUOTE]
