GM Drop-in Barrel for TC
Eric Krewson:
As an example; I built a .54 Lancaster rifle, somewhere along the line I trusted Rem Oil to protect the bore after a meticulous cleaning. I checked the gun 6 months later and the inside of the barrel looked line a red potato farm, tons of rust.
Here is the gun, first build so it is a little sloppy;
I scrubbed and scrubbed and couldn't get the rust out so I got agressive, I loaded a scotch bright pad patch with soft scrub cleanser and went to work. OOPS, I could see metal come out of the bore with the patch. A checked with my bore scope showed I had rounded off the corners of the lands, the rust was gone and a little pitting remained. My starting out goal was to fix the barrel (Rice) or ruin it so I had to replace it.
Here is a bore scope picture after I finished with my aggressive scrub, you can see the pitting;
I shot every load I could think of (I thought) and the gun wouldn't group. One day at the range I miss-set my powder measure for what I thought was 90gr and shot a cloverleaf. I looked at my measure and it was really set on 80 gr, BINGO!
The only thing this gun will shoot accurately is 80gr of 2F, a .535 ball and a .015 ticking patch.
It does real well, the tight group is 3 shots at 50 yards, I pulled the one that hit to the left, the two to the right I held steady on.

Good luck with the work-up! Keep us posted. I shoot mostly a .50 cal T/C Hawken, and 3 .58 cal, my first Navy arms "Buffalo Hunter", a custom(?) long rifle with a Douglas barrel, (both shallow grooves) and a custom flintlock with a Bill Large barrel and a Hadaway lock. All of them are better shots that I am! But they will still stay in the black off the sandbags! Been shooting round balls mostly in all 4, but if you shoot, you clean! :-M (lol)

"after a meticulous cleaning", been doing this BP thing for 50 years, never had any rust in my bores until the one mentioned above.
Eric Krewson:
Seeing as how I now had 2 new TC barrels and one stock I decided to locate another stock with all the hardware and make two rifles. A quick request on one of the M/L forum classified and one appeared. I bought it and tried to install my new drop-in barrel into the stock, it would go but was a very tight almost forced fit. I probably have a little more in the gun than it is worth but if you want one you want one.
I decided to relieve the barrel channel, I tried a scraper but it didn't do an even job so I used a finger nail emery board which worked well but clogged up too quickly. Next I used a popsicle stick with some 200 grit sandpaper which worked quickly and easily.
A little sanding, a tru-oil refinish and I was good to go with an easy drop in fit.
Eric Krewson:
I made a variety of peeps for the new barreled gun, the factory rear sight is too far back for my peep to work like I had intended. I am gong to try to find a buckhorn that fits the TC sight holes, one that runs down the barrel a bit.
