He uses TJ Enterprises liners I believe. They are about the best available. Hammer forged. They make a specific liner for 22short (1-20" twist).
Track of the Wolf (the Muzzle Loader supply place) sells TJ's liners.
Here's a link to the cartridge liners:
Barrel liners: breech loading rifle bore liners - Track of the Wolf
Or you can buy them right from TJ Enterprises for a bit cheaper price:
TJ's Enterprises
3652 Neltner Rd
Alexandria, KY 41001
(859) 635-5560
(no website)
The Track of the Wolf link will let you see the selection anyway!
Brownells 22rf liners were (still are?) Redman Rebore/Relining Mfg brand liners. They were a standard 8mm (.323) OD. Button rifled I believe.
TJ's 22rf liners are 3/8" OD (.375). That gives you some extra to work with in some applications.
Some find that extra dia a pain. It's easy for the DIY'r to drill a N drill hole through a burned out 22 bbl with a piloted drill and get a decent job.
Stepping up to a 3/8 starts to put a strain on the old Black and Decker!
Just some thoughts
