To briefly revisit this, I took Fiver and Ian's advice and fireformed all the cases I've formed for this rifle so far. Seems to me the shoulder to neck transition is visibly sharper. Look good to me. They also shot pretty well 1 3/4 group plus 2 fliers that I'm sure were me. 50 yards from a rest. 49 rounds[1 case AWOL]. Wonder what kind of velocity these are? 12 grains of Promo under a RCBS 200 RF. Mild to shoot, nothing like 48 grains of 4350.
