I was pulling some 50 BMG rounds I had loaded last winter which ended up being too hot for Texas summers. I use H50BMG for my powder, however I pulled down some from a different batch (purchased from someone, not my reloads), and the powder was a fine grain ball powder. It looked very similar to Ramshot TAC, yet just slightly larger balls. Anyone know what powder this might be? They cycled fine in my 50.
