I have a 1:7 twist 8.5" sbr blackout and I'm going to load a hunting round. I've bought some of the Barnes tac-tx 110grn black tips, which are expensive enough I'd rather not use more than I have to in load development.
I have h110 and 1680 for powders. Probably going to use h110. My hangup is on the short barrel. I've never loaded for an 8" rifle barrel before. All data I'm finding is for 16" barrels. Barnes says use 18-20 grains, hogdon 18.4-19.4.
Should I step that down a bit for the short barrel? Like 16-17 grains? Or just stick around 18? I'm currently thinking try 4 at 17.5, 4 at 18, and 4 at 18.5 and keep whatever seems to work the best. Does that seem reasonable? (Reloads at nearlty a dollar a round. Woof. I miss my cast lead wheelweight bullets already)
