I got a bottle of American Pioneer powder last year, I immediately started having consistency problems. I thought it was maybe my scope, then I thought it was the sabots I was using. Last week I fired 25 shots from It and finally ran out of AP. Today I bought a bottle of triple 7, and Hornady 250 grain sabots. It took me 8 shot to be dead on 2" high at 100 yards. I don't know if anyone else has had this happen but I've never had this much trouble at the range in my life. AP is worthless in my opinion.
