Thread: Chamber casting material ?

I'm fairly certain its 357 mag chambered.
I went and dug through a heap of old cartridges I collected when I was a keen young lad and found a couple of 357 mag loaded rounds and empty cases.
They are a very nice fit at both ends.
Chamber fit is perfect and projectile is a tight fit at the muzzle.

So when I get it all going it will be a fun gun to run on cowboy 38 specials

I think that problem is solved for now but I will add some BROWNELLS - CERROSAFE to my next order of bits and pieces
