Had the Single-Seven to the range this afternoon and put 4 cylinders full through it (I was kinda pressed for time). The first cylinder was all over the place. I shot that first cylinder from the bench, then I stood up and shot from the standing leaning against a range shed supporting post to steady myself and the gun would actually group but still, it is more like several groups in different places as if each chamber is shooting its own group. Further, the firing pin strikes every primer off center. I wonder how much that might affect accuracy. Ammunition today was the Federal 100 gr. load instead of the 85. Both bullets are the flat point soft nose. You can't tell them apart looking at a loaded round. Maybe handloads will be better...

I am not very found of these Federal loads. Some rounds seem to have a "bottleneck" in the case about 3/8" above the rim. When you drop them in the chamber, some will just drop in and some will "hang up" right at that point. Also, when shooting, the cylinder will sometimes drag and I am pretty certain this is a primer dragging across the recoil plate.

The club president was there this afternoon and he thinks the trigger pull is pretty darn heavy. I think I will take it in and measure it tomorrow at work. I didn't think it was all that bad.

I also took the CCI A17 ammo to try in the Contender .17 HMR barrel. It shot quite a bit higher than the standard .17 HMR ammo I was trying earlier but grouped inside of 1 inch at 100 yards despite my use of my old Weaver 1.5-4.5 scope on a standard small-bore target.
