How Much to Rechamber Rifle

[BarnesX.308]

I've had a Weatherby Vanguard in .300 Wby Mag for a while and I'm starting to get bored. I want a new and more powerful rifle. How much would it cost to rechamber/reream/rebarrel a .300 Weatherby to a .340 Weatherby? Thanks.

You're talking two different bore diameters. You would have to re-barrel, not re-chamber. Unless you want to put a lot of money into ityou'll be better off buying a new rifle.

last 2 barrels I've bought were
kreiger senduro weight 6.5 cal. fluted SS 29.5" longinstalled was 588.00 bucks
Lilja 30" .284 #8 Fluted installed was 687.00
This incledes chamber and crown, setting headspace, if you go that route you would be better off to add another 150 bucks to true and accurize the action and square the bolt face, and lapp the lugs.

Back in the 1950's and 1960's, there were a number of barrel makers who would ream/re-rifle a barrel out to a larger caliber. One of the most common was taking a shot-out 30/06 barrel and reaming it up to .338/06. You almost never hear of anyone doing this these days. Depending on the quality of the new barrel, a complete re-barrel is going to cost you in the $325 to $450 range.

To have it rebored, re-rifled and the chamber opened up, it will cost you about $350.00 or so. A new barrel would cost around $400.00 UP. That's more than a Vanguard would cost!

The problem with reboring is the time you must wait for the work to get done, but a rebore job by a reputable 'smith is usually excellent! Often better than the barrel was in the original caliber.
