Wow. Miller is right did't think. .708 is what my Winchester Xpert N-14's measure. But, I wonder what they are????

Bob; Just a thought, Do you supose, that for whatever reason, that was from a lot of paper shells, perhaps special ordered, to fit a "B-Size" chambered 14ga gun. That .708" is .015" larger than a nominal 14ga bore. A paper case is normally made with some clearence to allow for easy chambering & extracting even with a small amount of swelling so would seem to be in the ball park of a B chamber, though I do not have actual dimensions for same.
