I'm running two different loads in my AR with H-322, one with 55 BT's, the other with bulk Hornady 55's. Works just fine, go for it.....
Aalf, If you don't mind my asking, what's your load with the 55gr NBT's?
I'd rather not say, 1st due to me shooting moly plated bullets, and 2nd my lot of powder dates back from a long time ago, and is not like the current extreme version.
