I think I am going to have Bobby Hoyt reline the barrel on my 1869 Springfield 50-70 trapdoor. While it's an antique gun, it's a shoot-able antique, and I'm wanting a new bore that will shoot the more standard .512 bullets of today.
If one were aiming to shoot in the neighborhood of 475 grain bullets,,,what would be the preferred twist for this weight bullet ?
Thanks folks
Deadwood
