If you are considering having your rifle rebored to a larger caliber you need to know that there is some customer assumed risk!
Seldom are there any problems associated with the process, but, you need to know that occasionally I do lose a barrel during the rebore.
1. I do not know exactly what the steel content is in factory barrels. Each manufacturer specifies their own mix of steel, and seem to change those specifications at irregular intervals. Most modern steels cut smoothly and cleanly, but some do not.
Barrels that often do not cut cleanly---
Sako, Husqvarna and late model Weatherbys use a type of steel for their button barrels that is unsulpherized, it cuts to a rough finish.
Old Winchester barrels seem to have hard and soft spots the entire length of the barrel. They often will have small tears in the bottom of the groove.
Old Flaig barrels have a high vanadium content and do not cut cleanly.
Hammer forged barrels occasionally have microscopic air voids created during the forging process.
Ruger Stainless Steel button barrels.
Mauser military barrels about a 50/50 chance of cutting cleanly.
2. The reboring process is a multiple step machining process involving up to 25 reamer pulls to get your barrel up to the new bore diameter. Then the re-rifling process involves the rifling cutter moving in and out of the barrel approximately 300 times (50 times per groove). Ocassionaly during this process something goes wrong. The rifling machine is automatic in its cycling and if a problem occurs, it usually ruins the tooling and the barrel before I can stop the process.
With all of that said, if we have not scared you away—The reboring process is an excellent way to restore an old rifle without having to have a new barrel contour reinletted into your stock, and having the gun reblued. It is generally a much less expensive way to have a caliber change done or to obtain a rifle in a cartridge that is not available through mass manufacture. Accuracy is generally better than original (see some of the rebore targets)
