Comment Emailed hodgdon for load data, they said use H1000 load data from their site for baseline. Worked from 72.5 gr to 76.5 grains and the bolt lift was slightly stiffer when I hit 76.5 gn. Load has performed sub 3/4 MOA on several range trips with changes in elevation of 2500' and temps from 55-75F. Have not tested the load cold yet. Standard deviation for 18 shots is running at around 15(not spectacular but the groups don't seem not to suffer at all) and no POI changes yet.
