I just went out and sighted the rifle in with the powder. Got around 2 1/2 inch groups at a 100 yds. with a red dot scope, so am happy with the powder. The H&R also loaded alot easier than when I used the Pyodex pellets. My only complant is that I wish they would make the granulation smaller. It was hard to get it to flow out of the powder horn and in the adjustable measure had to almost beat it out. Also had to check and see that it all came out. Is thier 3F smaller grained or is it like the 2F? Zeak
