I have a severly coroded [internal] .54 Renegade I bought second hand.I just got a GM ball barrel 1-70 and a TC 1-48 conical pipe.The crappy barrel I'd like to have someone rebore to 20ga with a jug choke.GM used to sell a 1" barrel like this but are now discontinued naturally.Anyone know of anybody that can do the job?Thanx Harold
 
I would think that any good machinist should be able to ream out the barrel. Or you might even be able to do it yourself with a brake cylinder hone and a lot of time.

Getting a choke that worked put into it might be a little more tricky though.
 
If you start now you will be done by Christmas with a hone, and it will suck. If your barrel is .54 now and you need to get to .615 you will need to ream it in a few steps, or at least thats how I would do it. I would think that most smiths can do this but they would need the appropriate reamers.
 
The GM barrel was .62 and the jug choke is similar to back boring.Cylinder bores can shoot full choke patterns.Like the Knight shotguns...........Harold
