I did not think about a set back and rechamber. I'll ask my gunsmith. I bought a new carbon fiber Proof barrel for it, but haven't installed it yet. Waiting on an action wrench.
Thanks Jeff!

My pleasure. I've done this successfully on a few rifles over the years. It buys you time, but eventually the rest of the barrel will be worn enough to replace it.
The one rifle that I have done this on the most is my Ruger #1 in .220 Swift. Boy you want to talk about a barrel burner, the old Swift is infamous for this, and for good reason. Lots of powder being burnt in a very small bore.
Results, however, are worth it for the performance it offers. Very old school, developed before laser range finders and scopes that can be dialed for specific ranges so easily. Your 6.5 Creedmoor is a superior long range cartridge in today's world, due to the technologies we have developed. Heavy for caliber bullets at moderate velocity, don't worry about trajectory, just dial the scope to whatever range the range finder tells us. Very effective.
The old Swift, however, relies on velocity and the attendant flat trajectory. Lighter for caliber bullets, not great ballistic coefficients, just get them going as fast as possible. The faster the flatter. Trying to shoot so fast that we don't need to know the range or worry about trajectory, out to three or four hundred yards. I keep mine zeroed at 300 yards, and can pretty much hold right on a rock chuck or coyote out to 400 or so without having to check the distance or hold over or anything like that.
My favorite load launches the 60 grain Hornady V-Max at just about 3,800 fps. That's kind of a heavy bullet for this chambering, but it is actually carrying more velocity at 400 yards than the 50 grain bullets favored by most Swift shooters (I can start those at almost 4,100 fps, but the 60 grain still catches up and passes it, velocity wise, at about 300 yards).
Anyway, enough of that. This is a pictures thread. I've shown it before, but here is my #1, sporting its third or fourth barrel. I burned out the factory barrel in less than a year (way back in about 1982), then went to Lilja from there. This one is 28" long with a 12" twist. The higher than normal velocities are due to that long tube. The two cartridges are the .220 Swift and a .223 for comparison.
