Berger 135 LRHT @ 2.805”, 39.0gr H4350 (various primers) = 2820-2850fps from 27” Brux 1:7.5tw. Still seeing linear velocity trends above that, so I’d consider it a mildly warm load. Been up to 2880, but don’t need to be there for this rifle. I am also using the Blackjack spec reamer with 0.131” FB, for reference.
Just ordered a 24” Fluted Sendero for NRL Hunter, and need to make PF with that so I will push a little harder to get to the 2820fps minimum needed. I want to run Alpha brass in this barrel, mainly to help keep it from being interchanged. Does anyone have any comparison between Alpha & Lapua brass (6.5x47L necked down)? I may try Varget for this purpose too, Im slightly compressed around 40gr, and may not have enough case capacity to meet PF with H4350.
