HA! - I'm losing it, Ripp. Also forgot about HS Precision - there are probably more who cut modern rifle barrels, which is why I noted, 'as far as I know'. I should have said as far as I can remember, so that's Kreiger, HS Precision and Badger.
Badger barrels are preferred (or popular) by most of the long range black powder ctg. shooters, however the Green Mountain .45 barrel on my Sharps is competitive, shooting as well as the 'preferred' make. Any time you get MOA or sub MOA with lead and black powder,(especially with my eyes and iron sights) it's a good barrel.
