I just got my reloading gear from my father, he dont use it any more. Its an rcbs press. He used measureing spoons for powder. He mainly reloaded .243 and 30.06. In one box there was a 4lbs can of hercules unique powder brand new. I tried researching it. It takes me to alliant powder and speer bullet combos. Can someone give me some insight on the hurcules and the alliant combos?
