I'd like to say it was 25 yards but...I'd be lying. It was only 10 yards and 5 shots. I can't see the front sight and the target with glasses on much past that distance indoors. If I could shoot outside, I could extend the range some more. Man to be young again! I'm mostly just looking for consistency when shooting at that range. I need to find someone with good eyes that can shoot to test these for me.
7.6 gr of AA#7 did nearly as well. My AA#5 and HS-6 loads were at least twice that size or more.
