7.62x51 grenade cartridge load data?

[Stray03]

I have been looking for load data for grenade launching cartridges for the .308 / 7.62x51 but so far have only found the load data using military powders which I have no access to. So I was wondering if anyone here has played with them, and if so how they load their own.

Thanks.

anything blank will work a small amount of a shotgun powder will work how much well idk

I don't like the idea of using a blank to launch it cause of the fast burn rates. I'd like for them to match the military load.

The best I found was this:

US 7.62 NATO Grenade Launching Blank is loaded with (alternative loads) 37 grains of HPC4; 40 grains of IMR 8097; or 45 grains of WC830.

Does anyone know the civilian alternatives to these powders?
