[QUOTE="ken snyder, post: 576098, member: 26019"] I always stick to the upper mid range loads with the 338 LM. For the 300gr SMK I am currently using 76. 4 grains of IMR 4350 When we had the somewhat recent powder primer shortage I found equally good results with 79.2 grains of Re 22. These are Sierra upper mid range load recommendations, The published velocities for these loads has always proven to be a bit on the high side for the Chamber dimensions I choose. The nice thing about upper mid range loads with this cartridge is that they provide a very large sweet spot of consistent velocity spreads over a large range of seating depths. and have found them to be highly immune to a fair shake more than modest barrel erosion. Now you have my secret sauce recipe! The 338 LM is a modest velocity cartridge by super magnum standards but its inherent accuracy is something that the big kids on the block have to prove themselves against. P.S. for obvious reasons I disclaim every load recommendation that has ever been written or spoke including my own. [/QUOTE]
