I'm working on reassembling an old .45 cal. cap lock with 40 inch barrel. It uses 3 pins to retain the barrel and has a section of 5/8 inch hardened bolt as a breech plug. I recently got hardened steel pins from TOW for the barrel. Question is, if the tang is affixed to the stock with screws but is not attached to the barrel in any way, what happens if the rifle is fired, even with light loads? The barrel and breech plug make full contact with the tang. Everything else is good but the barrel is not attached to the tang. This is a family heirloom and I would like to shoot it a few shots on special occasions, but it will be mostly a wall hanger.
 
as long as it makes FULL contact all is well. i would slot the tennons a bit in case there is slight movement of the barrel so as not to split the forearm. you could always tack weld the tang to the plug. see what others think.
 
In addition to the tenon slots to allow barrel movement, I'd want to make sure the end of the breech plug completely and evenly contacts where it interfaces the stock in the barrel channel and tang inlet, so it's the stock itself taking the major recoil force, not the tang and the tang bolt.
 
Have to agree with Phil on this one. The stock doesn't support the barrel it is actually just the opposite the barrel supports the stock. That area around the breech is a very weak area it won't take much of a bump to crack that area.

Pictures please.

Without clear detailed photographs (or a hands on examination by a competent tradition muzzleloader gunsmith/stocker) to help folks figure out what you have, best answer is NO, DO NOT shoot your family heirloom gun as you run the risk of turning it into firewood.

Now, if the barrel, breech plug and tang are properly fitted together and inlet/bedded properly in the stock, and the stock is solid, a few light loads may not be a problem, but with what information you have provided, no one can tell you for sure.

Is the breech plug made from a hardened bolt a recent addition to the gun? Is there a reason it doesn’t attach to tang?
