My Jeffery had a second bbl made in the 1960's for .458wm which was re-chambered for .450#2. I was thinking about trying to regulate the 550 projectile at 2150fps in this bbl. I think it would come close to 500NE energy and have only moderate pressure.

I'm only thinking about this as a way to add value to the second bbl.

Thoughts and comments?
