Green Mountain are custom barrels?
:crackup:
I don't think you can call a cataloged - like as eight peas in a pod - barrel that you can pull off the shelf of any of nine different supply houses for drop-in fit to a mass produced stock a "custom" barrel.
But, they are nice. Better than OEM. At least you can get the rifling in a slow twist.
Custom assembly, I suppose. Like putting a Chevy body on a Ford frame.
Ain't much wrong with the T/C barrels, really. Some chatter marks for sure but they shoot better than I can hold with the proper loads.
The only Green Mountain barrels I buy are ones that TC doesn't already make...both TC's 1:48" and 1:66" barrels are excellent...I have three 'GM drop-in' Hawken barrels because TC didn't offer them:
.54cal Flint smoothbore
.58cal Flint round ball
.62cal Flint smoothbore
All my TC barrels have a better fit, polish, and bluing than any of the GM barrels...it's almost like the bluing on my GM barrels is sprayed on, instead of soakd in.
For example, I tweak my lock mortises to get a tight metal-to-metal fit between the pan and breech plug on every Flintlock I get...when I finished sighting in the new GM .54cal smoothbore this weekend and lifted the barrel out to clean it, the pan scraped some bluing off the side of the breechplug...did that on the .62cal as well...but it hasn't happened on a single TC barrel yet.
The very bottom and bottom-side flats of the breech plug that are not visible are not finished to mate smoothly with the barrel flats...only the very top and top-side flats are sanded to mate smoothly with the barrel flats that are visible when holding the rifle.
The wedge pin tenon is kind of a large klunky thing that I have to remove and sand down smaller so it rides up higher out of the way of the ramrod when it slides in under/past it;
Had to remove and shorten the under-rib on one of the GM barrels so it would "drop-in" to the Hawken stock and clear the nose cap;
And they come with black thimbles & black ramrod which I have to replace to match the brass Hawken furniture...so in that sense...after I'm all done, I have "custom" GM barrels.

But they function fine
