Went to the range Saturday with high hopes of my loads consisting of IMR 7828 and Barnes 100 grain TSX's showing me good things out of my Mark V.
Shot loads in half grain increments from 71 - 74 grains. Best group I got was with 74 grains, but it was over an inch. Extractor mark was starting to show as well...so I have two more suitable powders on hand to try. Which one would you try first with the above bullet?
