I am having trouble lowering my SD/ES with my match AR. Right now it's around 11 and 25fps respectively, and I don't know what else I can do to get it down. I've also noticed during load development it's often the case that the load with the lowest SD isn't very accurate and vice versa. The gun shoots anywhere from .3-1.25 MOA. I've realized too that a lot of times in a 5 shot string if I could eliminate 1 of those velocities my SD/ES would be cut at least in half. I have no idea how but recently 23.8gr of varget gave me 3inches of vertical at 100yds over 5 shots with a 9.2fps SD?? Then 23.9gr gave me 0" of vertical and .5" of horizontal with an SD of 11.3fps. This is what bothers me and why I feel like I could easily still improve. All testing is out of a Green Mountain 20" drop in barrel with a Labradar at 100yds. How I reload: -LC 08 brass, once fired, stainless pin tumbled, resized to max headspace for my rifle with Hornady dies. Results in .003" neck tension. -Trim to 1.750", chamfer, debur with Frankford Arsenal rotary trimmer -Uniform primer pockets to .020" and debur flash hole -Prime with CCI450 -Charge cases with Varget to +/-.02gr accuracy with Gempro250 -Weigh 77gr smks to +/-.04gr and seat with Hornady seater -Finished rounds are checked with comparator for base to ogive within +/-.0005" I'm switching to a Redding body die and lee collet neck sizer, just waiting for them to get here. I'm aware of a lot of other things guys do when reloading and theories behind them, just don't want to spend the money until I'm convinced it will help. Data and/or anecdotes with your suggestions are most appreciated.
