I'm using QuickTARGET software, it comes with QuickLOAD.

The scope that came with this gun started wandering noticeably today at 20 yards. Wasn't sure what was going on, mounts were all tight, but internals must be wonky.

I pulled the scope off and went to the iron sights, it tightened right up.

I think that kind of explains why I was not seeing any drop at the 50 and 60 yard targets yesterday.
