That is a very good site for military loads...
Any and all of those powders will probably damage your Op-Rod and you don't want to have to buy one at today's prices!!!I also have IMR 4350, RL25, RL22, RL19, H4831
TenDriver, I tried 46 and 46.5 grains of IMR 4064 and found that extra .5 grains had a huge effect on my group size. You might want to check it out for yourself.Mine has been 46.0 of IMR-4064 with a 150 gr bullet.
Last this subject came up I attempted to find the maximum recommended 4064 load with that bullet and got a smarmy answer of "when your rifle blows up", and chastised for trying to find it.
Good luck....
