Reboring 15/16ths Round Barrel

[PeteDavis]

Hello All

Last year I used Bobby Hoyt to rebore and rebreech an older CVA Mtn Rifle barrel. He did a great job.

I have in my possession, a T/C Tree Hawk with a .50 cal. barrel that measures 15/16ths OD. Is there enough metal in the barrel to allow a rebore to anything usable? I do not know the breech plug dimensions.

You can go to .54 for sure, which is useful. Going further depends on the guy doing the work, and if he trusts that you won't load it with a two or three hundred grain charge, double ball, blow it up, and then blame him. I think .54 in a 15/16ths barrel is kind of the industry standard maximum, but I could be wrong. .58 would be a nice light barrel in 15/16ths, and make a really cool rifle. Perhaps your Bobby Hoyt would be fine with .56 caliber, which is a smaller increase over .54", which would also be very cool. ?? You need to ask him, which you have to do anyhow. !!!!

The only person that can answer that question is Bobby Hoyt.

Yes but it doesn't hurt to prime the question here. The other issue he can answer would be the potential depth of the mounting holes for the sight and the breech threads. This barrel I am pretty sure is a clone of the New Englander and Grey Hawk barrels and he has bound to have done a few of those . Thanks for the answers and when I unpack this I will report here.

It's amazing how badly trashed most 1970's and 80's muzzleloaders got in average hands. The gun shows are chuck full of badly pitted muzzleloading barrels. I did it myself and so have most of my local friends. I think the boiling hot water cleaning over pyrodex and the three-year put away did in the most of them. I have since learned the lesson most of you on this site know. Clean, clean clean!!!
