I'm looking to duplicate M80 loads to shoot in my AR10. I've got 150 FMJ and assorted brass. What powder would be good, H4895, BC-2, etc?

Does anybody have any experience or issues with this ammunition, other than Berdan primed and not easily reloadable? There seems to be some good deals on it. Thanks

400+ M80 ball PMC surplus. 300 +/- Malaysian L2A2. 300.00 cash or trade for optics or AR lowers. Jackson metro area. (Ammo cans aren't included)
