The other day was out testing loads for a 308 and something occurred that surprised me, hopefully somebody out there can give a reason for what I though was strange. One five shot group with 42.0 Varget was about .75" above the bullseye -- the following group was 42.5 grains Varget and that one was perfectly centered in the bullseye. I thought it weird the group with more powder would be lower on the target -- now I am 99.99% sure that I didn't just shoot the wrong targets with my loads and everything else about the loads was the same -- bullet, case, primer, jump to lands, seat depth, ... the only variable there was .5 grains of Varget. Why would the hotter load shoot lower on the target?
