Range Report:
I did some general function test shooting, and everything seemed fine. No apparent feeding / firing issues with around 60 rounds fired (all factory loads, Hornandy AMAX and SST.

I did not have the best setup for accuracy testing today, but I did shoot a couple of 3 shot groups off of a bipod with a rear bag (prone). Both groups measured about 13/16" edge to edge (at 100 yards) or about 0.8 MOA. I think I can do better on a bench with bags. I am encouraged at its accuracy potential.

THIS TARGET IS TURNED ABOUT 90 DEGREES RIGHT



THIS TARGET IS TURNED ABOUT 45 DEGREES RIGHT


I have come to the conclusion that I need a chronograph and some reloading equipment. Shooting this thing is addictive and expensive!
