[QUOTE="codyadams, post: 1224524, member: 87243"] I have a .260 AI, 30" Krieger 1in8 barrel, using Berger 140 VLD's and H-4831sc. I'm using CCI 200 Standard Large Rifle primers and formed Lapua brass. I have loaded from 47.5 grains up to 49 grains in .3 grain increments, and the ES never improved. My most accurate load is 47.8 grains going an average of 2,980 fps, at 100 yards it shoots in the .1"-.2", but my ES hangs around 25 fps for 10 shot strings. Every charge is weighed, CBTO is very consistent, everything about this load is very consistent accept the extreme velocity spread. My first thought is to try a different primer, and if that doesn't work I may try different powders, thinking IMR 7828, Reloader 19 or 22, or maybe Win. 780 Supreme. Any suggestions on what to try? Anyone else ran into this issue? Any help would be appreciated, My 2 goat tags and deer and elk tags are creeping up!! Thanks all!! [/QUOTE]
