 the Ruger GP 100 match champion in 10 millimeter. Will it shoot 40 Smith and Wesson and so that's what we're going to figure out now I've got some loaded up on speed clips we're gonna we're gonna check that out let's load up some 40 and see how it goes with six rounds of 40 Smith and Wesson and the moon clip you need the moon clips case will sink too far into the cylinder 10 yards away we've got 40 let's go so two did not fire from 40 and you can see that all of them have primer strikes the two that did not fire have light primer strikes
