Anybody reloaded AR15 and AR10 with IMR3031? I have some info from Hodgdon’s, but would appreciate some feedback from someone with actual experience using IMR3031 for reloading AR15 and AR10’s.
I would be using Hornady 62gr FMJ’s for the AR15 and Frontier 155gr CMJ’s. AR15 16” barrel, 1:7 twist. AR10 16” barrel, 1:10 twist. Would appreciate feedback from actual users.
