The breech should have a wall thickness of at least the bore diameter which in your case would be about 1.75 inch. Drawn Over Mandrel (DOM) seamless steel is the usual choice. The breech plug should be threaded in place, no welding. The plug should extend at least the bore diameter into the bore and more is better.
