DD, we certainly are not complainers, so, after talking it over, Mike and I have agreed to try your club's method and we sure could use some tips in that fine art. We understand the basic method which your excellent photos clearly show, but any "advanced tips" would be appreciated for sure. Also, I think we may have missed the posting detailing the distance you shoot at. We will get some photos and sketches together for a "how to" on the iron sight OR scope base that we made. Rickk is right; you can modify it to fit almost any cannon contour.
Regards,
Tracy and Mike
