OK I did a better measurement with a really tight patch. Wouldn't ya know it is a 48 incher. I stand corrected and happy too. I'll be running round balls as soon as I can get a mould. The local salvage yard sells clean soft lead for 50 cents a pound. One of these days I'll learn how to post a picture. The only wear on it is that somebody dry fired the nipple enough to mushroom the end.
