[QUOTE="D Scott, post: 852074, member: 35050"] I am reloading for a Savage LRP in 260, I have been shooting Noslers custom comps HPBT in 140 gr, at first I was getting around 20 fps ES, but now after several reloads on the brass it seems my ES is starting to grow, I have changed primers, CCI BR2, federal Gold match, and Winchester large rifle primers, the CCIs are the best, aside from the differences primers can make, what else in the brass prep dept would influence ES, I am getting over 50 FPS ES now and I am seeing the increased vertical dispersion downrange over 4 inches at 600 yards, I did get some ES down at 6 FPS with hornaday A max , with the same brass prep method Have been getting groups at 100 yrds in from 1/2 in to 5/8 inch Usiing Forster comp FL size and seater dies, I FL size each time, with expander ball Tumble with SS Media for 2 hours or so using 4831 sc 44.8 gr / nosler 140 CC HPBT seating depth doesnt seem to effect ES, or accuracy using a magnetospeed chrony, it does cause POI shift, but would it decrease accuracy ? since its attached to the barrel ? thanks in advance , any feedback or advice would be appreciated, Scott [/QUOTE]
