I am pretty happy with it. I tried a variety of loads. Some were not very good. Factory 32 H&R Magnum did well. 12.5 Grains of H-110 pushing a 100 grain Swift A-turned in solid results at 60 yards. The Leupold behaved like a Leupold. It did whatever it wanted to do when adjusted. Up and down was pretty good. Left and right was a mystery. The target spot was on a target, not my tractor, when I shot it. That was my last 3 shot group.
Saddlering, it wasn't perfect cycling H&R Mag or long. It was with 327 Federal. With long, as long as the gun was level and the lever worked at medium speed it was perfect. The H&R would jam up on the last one if I was cycling as fast as I could without firing. It didn't seem to be angle sensitive.
