Was just looking for what the sierra manual had for a max load, but that helps. Right now I'm running 42 grains of varget with the 100's. Very hot load compared to what the Lyman manual, it lists a mx of 34.5 grn. I'm wanting to try 4350 and 4831sc though and was just wondering what the book says for max. Guess I'll either buy it or just start with what the Lyman book says.
