Your primer pockets should be good more than three firings with safe loads.
I know they are a bit warm. I dont think one grain will be enough in extra pressure to make a difference. This gun is a hunter. I shot 5 rounds out of it last year. My brass lasts atleast 4 reloads before i anneal them and even if they didnt, oh well. With the amount of shooting I do with this gun it will last a really long time.
I just might load some shells for my gun at 70 to see what the velocity changes to. I know the group went from 1.25ish to 3/4 with the extra powder so I like the accuracy I'm getting.
I have bullet pushed out as far as I can and I'm still a ways from the lands. That's the.bad thing about the Browning's, the magazine box limits how far out you can seat the bullet.
