The Reising fires perfectly in semi-auto, but it still hiccups a bit in full, with the occasional round not sliding completely up the breech face as the bolt closes. And it's so slight that just the faintest pressure from me on the action bar is enough to get the bolt to close properly on the round stopping it. The breech face is pitted,so I'm going to polish it and see if that doesn't cure this last niggling little problem.
Almost fixed. Almost working.
And in semi, I was using it to bat a tennis ball around on the 25m berm. Put the front sight post just under the tennis ball and squeeze off one shot and watch the tennis ball go into near-earth orbit. And the Reising is accurate enough to do that all day. Try THAT with a Thompson or other open-bolt subgun.
