If I get some time one of these days I may load up a few more and see how it goes.Hodgdon lists 14 different powders for the Barnes 85 tsx. The data can be used to load your 80 gr. imo.
IMR 4451 produced the highest velocity. Wonder how accuracy would be?
I use IMR 4350 & IMR 4831 in Win brass with Br2 primers and Berger 68 & 90 hpbt match bullets. View attachment 148957
