expirimenting more to see what happens with the newest batch of gap4s brass.

Norma 300 RSAUM necked down. On the 7th cycle, no loose primer pockets yet. Estimating a mild load because I have a 29" barrel, a longer freebore, and 140's are at 3175 fps with Retumbo. 3275 fps was easy, that was on the 2cnd cycle, but bullets were whacking out/blowing up occasionally at that speed.
I have 5 firings on Hornady brass that I've bought this year, so don't know what Generation it is, running 140's @3120, had them @3160 but backed off a little. Primer pockets still seem tight. I anneal after every firing.
This brass is marked GAP 4S. I just bought a brand new lot that is on firing 1. I shall see what happens with those over the short term.
