[QUOTE="calinb, post: 634421, member: 31242"] Here are my first QL runs. First I ran 2.840" COAL and then increased it to match a shank seated depth of 66% of the Berger 180 gr. diameter, though I have no idea if that works well with the Berger. Seating it shallower results in a COAL of 2.971", which should still easily fit in an AICS short action mag (2.985"). The extra powder space does provide a little improvement in velocity using a couple of the bulkier powders, but the powder capacity constraint isn't as much of a problem as I thought it would be. I used the lower 63.9 grain total case capacity for these runs, which I suspect is fairly accurate. I wonder how things will look with the new 195 gr. Berger! These 7 WSM GT runs use absolute max. pressure of 64,542 PSI (7mm WSM SAAMI max.) and 105% max. filling (compression) ratio. The 7mm SAUM runs use the SAAMI 65,000 PSI maximum. QL always reports pressures close to max. as "DANGEROUS." 2.840" COAL: [ATTACH]7966.vB[/ATTACH] 66% shank seated depth/2.971" COAL: [ATTACH]7967.vB[/ATTACH] 7mm SAUM 2.985" COAL (max. SA mag length): [ATTACH]7968.vB[/ATTACH] 7mm SAUM 66% shank seated depth/3.142" COAL (LA mags only): [ATTACH]7969.vB[/ATTACH] [/QUOTE]
