Barrel for a Hammerli 208s??

I was browsing the site for Larrys Guns (AKA Red Feather) and came across an entry for a Barrel.
I know the Hammerli 208 has a screw in barrel which is so well fitted that it is hard to see where it joins the frame.
I also know that these were all individually fitted and I wonder if it is easy to just screw in a new barrel.
So what is this barrel which is available for a Hammerli 208s

Jerry Keefer did, but the First option is reline the Barrel. sadly Jerry Passed away, was a Innovation Master. David sams reline .22 barrels and Alex Hamilton in Texas.

That is probably barrel blank for relining. Dave Sam's is the guy, but 208 should shoot under 1 inch with stupid high round counts. 100,000, 200,000 and Maybe 300,000 rounds just follow the advice written by Larry. Clean every 500 rounds and never use bullets that have been on the ground.

I wore out a new 208 barrel. At 120k rds it barely held 1.5" with best lot of Eley Tenex the AMU had. It was over 2" with everything else. It had only shot Eley and RWS for its lifetime. Sams does a great job lining barrels; I own 4 barrels he relined.
