Shame on you Bronko. But I guess doubters will always be with us.

Yes, I was using open sights. I took the Lyman peep off for this shoot because it would have given me an unfair advantage. The group is a little larger than my usual at that distance. I guess the 30 m.p.h. variable cross wind had more effect than I'd expected. Also, I think my eyes are starting to lose some acuity. I had a small bit of difficulty focusing on that one-inch dot at 300 yards.
