Garand match load data from the NRA.
http://masterpostemple.bravepages.com/M1load.htm high charge data.
http://cartridgeloaders.com/article/...he%20NRA).html lower charge data.
165/168 grain FMJ, HP or SP bullets 47.0 to 48.0 grains IMR 4094
173/175 grain FMJ or HPBT bullets 46.0 to 47.0 grains IMR 4064
These are middle of the range loads that meet the pressure needs of the M1.
I think they are a good starting place with the components you have on hand. As always look to Hodgdon's data for starting loads, and work up until accuracy presents itself, then stop.
