Okay I'm thinking of making a extended range muzzleloader out of a ruger #1. I need a little gunsmithing advice. The setup up on a #1 should make the ignition very simple. Of course removing the used nipple would be more time consuming.

My Questions are.

I shoot percussion muzzleloaders. Would a 209 primer stay together for easier extraction?

The barrel. Would I be better off Having a blank from scratch or buy a 50cal. barrel and screw in a nipple post?

Does a 45cal blackpowder cartridge and a 45cal muzzleloader have the same bore size? If so the cost would be alot less on the barrel making.

Thanks.
