As I remember, the cases would stretch about .005" at 76 gr, so I dropped it to 75.5, and the stretch went down to .002". BTW, I throated this DR long, so I could seat these 350 gr out to the second cannelure, to keep pressure down. Regulation is good enough for minute-of-boar--too bad about the 3" hole in the slab of bacon from the far side---bang, flop, done.
