Thanks, Pitspitr. At least my mistake didn't cause physical pain and the pain in the pocketbook is still under $100, but I still don't want to talk about it. Oh, and River City John, the "nice group" comment isn't funny. I don't want to talk about it.
By the way, I thought that I took the sight offset into consideration. I even had it mounted on my new tripod (which emerged unscathed), which I lowered slightly just prior to firing the shot. At least we know that the 220 bullet is suitable for any chronograph that wanders the face of my ranch. (Rats. I talked about it.)
