Yes I know a good outfit, sell the barrel and buy an MGM
With the cost of a barrel plus the cost of a rechamber, you're about at the cost of a custom barrel that's higher quality and exactly what you want. If you want to sell it later, rechambers are very hard to move without a heavy discount. Whereas customs hold their value really well in a desireable round like the k-Hornet
I'm not saying don't do it, properly done rechambers shoot great. But having bought and sold a lot of barrels, that's what I've found.
