Ron I'm going to try them first without sizing. Just wrapping. I've been messing with .451" and paper patching them for the .45-70. I ran some through the .457" sizer and some not. There isn't much difference in them except the tail is flatter.
I found that if I give the paper a little spritz of alcohol before I wrap, when it dries it holds its shape on the bullet as well as if I size them.
