Do we have a resident knowledgeable Winchester Md. 94 lever action person on the board? I've recently acquired a Win. Trapper .44 mag carbine with a small loading issue. When loading the tube, if you push the cartridge past the loading gate, you cannot push the gate open again to load another round. It loads fine if you leave part of the previous shell out and push the next one in with it...................?? Anybody got any ideas?
