I just picked up a spare cut off. It doesn't have a hole in it, but I've seen many on auctions sites that do have a hole in them. Any one know what the hole is for?
I have in the files, a couple of photos of a WWI German in uniform with a Lee inserting a round into the cutoff to demonstrate how the treacherous Tommies made the Dum Dums. I wish I knew the source.
