I‘ll also vouch for RMC brass. Absolutely outstanding. It’s turned brass, but at bore gun pressures the strength is not an issue. It does use a lot of material though, and metal prices are through the roof in the last 2 years. I’m impressed he’s kept his prices as low as they are for a custom product. When you consider that it is made for your chamber and will virtually never wear out it is a steal.

Brass for my papercase 10 bore 2 5/8 was surprisingly an off the shelf item and arrived in a few days. Being as thick as a normal paper shell, they’ll never need resizing.

I ordered 30 cases when I got my gun and have lost track of how many roundballs they’ve launched. For my thin brass 4 he made the first .8” of the case .0004” thick (to hold the bullet), then it increased to .03” thick and greater. Same result, no resizing needed. Plus, he has the measurements from my cast on file if I ever do want more.

450, please make a post when you receive your Greener. I recently acquired one those with a similar project in mind for this winter, and would love to hear your advice and ideas. I'd love to see and hear any detailsyou have the time to share too Alan! Thanks.
