Hi everyone, wondering if anyone has any starting points for the hornady 80 gr amax. I built a 223 with a bison gun works 1/7 25 in barrel specifically for the heavies. I've searched all over the net and can't find load data in any of my books. This will be single loaded and I've already got my "jam" dimension using the hornady tool. Powders I have available are reloader 15 and varget. Appreciate any help.
