Re: Suitable steels for monoblock?

Bill:
I am going to build a new monoblock and keep the shotgun barrels intact.
I've been looking on ebay, however everything I've seen has been annealed, the one that is heat treated is way over size, I might have to go that route.

Aromaker;
I will offer you some of my experience as in your profile you say that you would welcome help.
Use annealed steel for your building of the monobloc. Alloy steel such as you mentioned in general do not need to be heat treated for use as a monobloc, and doing so makes the machining very difficult--according to how the steel is heat treated. You can see photo of a 20-bore rifle I built (Bore and Paradox forums on this site) using 4140 monobloc. http://forums.nitroexpress.com/showflat.php?Cat=0&Number=225579&an=0&page=1#Post225579.
