When I ran out of Clays powder I replaced it with 8 lb's of "E3". I load 1 once taget loads for which E3 is perfect. IMO E3 burns cleaner. I will never go back to Clays for the 12 gauge no matter how much "Clays" powder Hodgdon ships in a few months.
E3 did have metering issues in powder funnels with baffles. I load on a Hornady 366 and have not seen any metering issues.
