If I recall, the Hornady manual gives garand specific loads. I've not seen it in person (I don;t have the complete hornady manual - just the sections on some calibers), but someone here who has it might be able to confirm.

I do know that anything over 49gr of 4895 would be what I consider "too hot" for prolonged use in a Garandicon. I tended to stay between 47gr and 48.5gr - the 48.5gr being the most accurate load I tested in my rifles using the hodgdon 4895 formulation.

Your mileage may vary though as each rifle will hit peak accuracy with a slightly different loading, depending mostly on bore dimensions and condition.
