Got to shoot somemore of these to day and settled on 31.1 gn of AA2200@2.298. They flat out make a raggedy hole consistanty. There running around 2460 fps which is good enough for me Also, I found that if you take your charged tray of cases and aet it on the center bolt of your running tumbler , you can settle the powder to get consistant ogive measurements. This will get you out of a slightly compressed condition. Now on to trying the Hornady 150gn sst
I'm going to ladder 27-30 grains of Reloader 7 and check for pressure signs while fire forming the brass at the same time, then check for speed on a safe load with formed brass from that load. Sound right? It's what I did with my 6x45, so it should work with this one.
