I tried about 20 diffrent types of ammo, cheap stuff, expensive stuff, hand loads,voodoo... you name it. It was ok for the 1st shot, after that, no telling where your shots were going. one of only 2 guns I've ever sold. The only good thing about it was, it functioned.
we even went so far as to lock it down into a test vise, that was owned by a local gun smith. the damn thing could not keep it on the paper. sent it back to ruger, they said it was fine, it was with in thier tolerance. That pretty much soured me from every buying another ruger product.
