Hey all,

I have a May 1943 M1 and want to load for it. My research thus far has found imr4064 to be a safe powder for it. The Lyman 50th shows starting charge for 150s at 48.0. I know that needs to be reduced, but by how much? Please don't give the generic answer for military thick walled brass.

Does anyone have a reference or a published article about M1 Garand loads? If possible, using imr4064 and 155 grain bullets?
