I cobbled some IMR 7828 together with 154 gr Hornady SST bullets today and these were my results.
Top left measures .555 as compared to the other at just over one inch. It's amazing what a half grain difference in powder charge can make sometimes..
But to be honest, I'm not sure that the "shooter" wasn't at some fault with the stray shot since the other two are so close..
Gonna go next week and "prove" my results...
