Wow, how the heck did I miss this post???
I'm sorry it's only 60 yards, but at the time I was shooting with uncorrected 20/55 vision.
Now I'm shooting with correction and trying to deal with a very blurry rear sight!
Those were Hornady copies of the SMK; I have real SMKs now and am playing with Varget loads. Still have a bunch of them I need to ladder test, starting at 42 grains Varget.
