Hello all, I will have a 338 rum in my hands shortly. 28" bartlien 9.3 twist. Today I picked up 500 berger hybrid OTM 300gr along with some nosler brass. looking for the 338rum reloaders to chime in on what is working well for them? On a side note I fully understand that no two rifles are the same and would need to back down charge weights and work up slowly, no issues there. I have h-1000 and retumbo to try. Any help with this would be greatly appreciated. thanks in advance for any advice.
