El Rojo,

Ditto on the pulldown 4895 and WC-846...

I use 4895 in Garand and WC-846 in .308 and .223.

The only thing to be aware of with military powders is that they are NOT canister grade, i.e. each lot may have a slightly different burn rate. Every time you buy from a new lot number you MUST "go back to 'zero'" and work up loads. The new lot just MIGHT be hotter than the last batch you used.

I have direct experience with this. Commercial canister grade IMR 4895 and two different lots of Military 4895 all require a different charge to give me a certain velocity with a 150 grain bullet in '06. The Canister grade seems to be about in the middle of the range. Spread is almost 3.0 grains. That's a BIG difference, especially if you are shooting at the top of the velocity/pressure range for that round.

Use them with confidence, but ALWAYS work up loads for each new lot # you buy.
