RUGER Mini-14 new scope sight-in fail! (Las Vegas) 03-14-2020

Purchased a new Sightron STAC 3-16x42mm with the MOA reticle and Warne quick detach rings for my old RUGER MINI-14. Things started out good until the front scope ring loosened up which I hadn't noticed until I had used up all the ammunition. The older Mini-14 has a reputation for mediocre accuracy so I kept thinking it was just the rifle. I now believe the rifle can shoot much better than what I was getting after finding the loose scope ring. Will take the rifle back out soon and verify!
