Alright Brotherhood, I need help!
Factory Sendero, doing load development for Barnes 168gr LRX. No reliable load information for this bullet, so I started at 78gr of Retumbo, and worked up. Best accuracy and consistency was at 83.5gr. Approx 5/16" group at 100yds, with all three touching
Avg velocity was 3290fps, with an ES of 9.5. BUT, bolt lift was fine, but extraction was tough, and there is very slight primer cratering and a very faint ejector mark. I think I can safely assume this is max load of Retumbo in this rifle!!! Is this safe enough to keep shooting, or should I try working with one of the lower charges that had a fair group?!?!
