I hope I've solved the problem. The left chamber was tighter then the right chamber. Now honed out to the same and polished. Going pheasant hunting next week. Will try it out. I did shoot a couple of the federal lit loads in my winchester superx2. The shells would slide in and out of the "elsie" easy. Oh yes even though they say they won't work in an automatic, they did cycle and eject in the Winchester.
