Thanks, folks! Yes, it shoots pretty well. Next I'm going to get specs that line up the sweet spot on the lens with the bore sight of the scope. My goal is same-hole groups or at least all the holes inside the 10 ring, not just breaking it. One of my younger brothers was able to do that.
Here are some targets from the current setup. The entire set of targets' (18) average was 198.1/200. This is only four, just to give an example.
I want to thank all and sundry for the things I've learned so far, especially about scopes from Iowegan.
