barrel reboring

[Rawhide67]

I get that, just pointing out that rechambering is different from lining a barrel.

When it comes to original smooth bore's that need a barrel refreshed due to rusting, I use a hone that I made and never had any problems with them. I always do a proof load to make sure they will be OK.
One time I had a 54 caliber Jukar flintlock that the rifling was in pitiful shape. I used the same hone to turn it into a smooth bore. I posted about it (don't remember what thread) and caught a lot of flack for running the barrel from some who must not have read about turning it into a smooth bore. When I had it at the range testing it, a fellow loved it and bought it from me. That was years ago and the last time I saw him it was still doing fine and he still loved it, although he was a black gun type.

Edit: I just found that thread, here it is.

Correct me if I'm wrong but 32-20 to 32-40 is a rechamber in a cartridge gun, not a reline of a muzzleloader.

It is also rebored or reline. A 32-20 has dia of 314 and the 32-40 is 321.

Gotcha. Reline and re chamber.
