After going to the range, I took 3 5shot groups was not so happy....every 5 shots I had 2 fliers. 3 shots were about 3/4 moa. its 9Degress F out this morning with a 3mph L to R wind. I used all steps to make brass and loads ALL the same. some of the LC brass is from diff years only thing I have not checked is case weight. im wondering if its me shooting? or the imr 4064 in cold weather, or seating (2.797) or scope (vortex 1x5) dang im going nuts now and my brain wont stop turning. 44gr seems to be the correct load(powder) any help or wisdom would be awesome!! set up: scar 17 (308) Lake city brass cci primers imr 4064(44gr) 168gr hornady hpbt Using single stage press, rcbs AR dies with crimp.
