CptCurl,
A very good article, Thanks for sharing it with us on N.E.
I've never shot any paper patched bullets myself, but I do have access to a setup, it's a swaging setup to swage pure lead bullets that are then paper patched up to 458 cal or so.
I probably should go and see the gentleman and make a few slugs to patch up to try in my 450 NE.

Regards,
David.
