Swage jackets from paper?

[Wayne Smith]

Back to the swaged paper jacket idea.
A company I worked for many years ago used labels made from an extremely tough rag paper impregnated with plastic.
In trying to tear one of these labels I found the material stretched quite a bit, perhaps enough to form a seamless half jacket.
The paper was also very slick, almost like teflon.
I had thought of trying this paper as a patch for a muzzle loader, but never got around to it.

I remember using that. We called it tearless paper, if I remember right. Do you remember what it was officially called? Might like to try some.

Any plastic would probably melt unevenly on the way down the bore.

Even other plastic based stuff (like Tyvek - flashspun high-density polyethylene fibers made from recycled bottles), wouldn't work well... At least I don't think so.

And the more I think about it there is nothing to hold the paper to the lead. As slick and strong as that paper was I can see it simply springing away from the lead once the bullet is punched out of the die.
