Thread: Barrel lining/ sleeving.

From what I have seen , sleeve is usually done for low power cartridges like 22 lr, and 25 and 32 calibre cowboy calibres ,often in single shot or lever action rifles.
Unless you were going to shoot trailboss and cast lead projectiles in your 25-303 I am not sure it would work.

But wait to see if some more knowledgeable guys from the forum have a different view on the subject.
