Dimon 66--yes, I took a rail for a 10-22 that has a little curvature to it, filed it flat, cut two more cross notches in it to match the notches in the Ruger rail on the Ruger 22/45 so I wouldn't have to move anything on the scope itself when moving the sights back and forth between the two guns.
1SOW--yep, I think it was about 31 yards, varies from bay to bay. Wind was tough. That's my excuse and I'm sticking with it. With the sight off the gun, you can see just enough of the rear notch to use the open sights. I could cut a deeper trough in the rail and it would work a little better but I'm too lazy. The open sights are definitely useful for slow group shooting, but not so much for transition drills.
The red dot is very high relative to the bore axis. There will be some dial in or hold off moving from 25 to 50 yards in Bullseye. Our club match this month, however, is just going to be at 25 so I'm home free.
