[QUOTE="Cadman458, post: 936969, member: 79144"] So i just started reoading this year and was wondering if anyone has tried a 130gr ttsx in a 308win with ar comp powder. what i have is: ruger gsr 308win with 16" bbl 1:10 twist and trijicon accupoint 3-9x40 scope lee single stage press lee dies lee safety scale (i weigh ALL my charges) lyman case trimmer once fired lake city brass fl sized and trimmed with swaged primer pockets winchester large rifle primers if nobody has tried this combination would it be safe to reference varget data and reduce the charge to take account for the thicker lc brass and the ar comp powder? from what i understand ar comp has a burn rate between rl15 and varget. if this is possible could someone recommend a starting load? below ill list some data from barnes, alliant, and hodgdon if it helps...
