Have a nice Rem 700 250-3000 that I've run about 70 rounds through. First 20 where Rem factory loads and I noticed on these and the reminder (handloads), a noticable expansion above the web. This expansion is at least .005 greater than the cartridge web. So I bought a No-Go gauge from Midway and low and below the bolt closes easily with it chambered. Next up is to try a field gauge but how much of an issue???
Otherwise it is shooting great. This is a hardly if ever used Rem 700 Classic (purchased thru Cabela's gun shop which they listed as a custom order) - it is very clean. Have pics listed in the small caliber forum under the 250-3000 thread. Has the best wood I've seen on a factory gun.

No big whup. Just resize only .002" (measured at the shoulder). If it shoots accurately enough for your purposes, just enjoy it. You can buy a lot of fresh brass for the cost of a rebarrel. If it is too loose, you could have a gunsmith set the barrel back two threads and cut a new chamber. Most factory rifles these days are chambered pretty much on the loose end of the spectrum of possiblities....

A skilled gunsmith or machinist could check the chamber with the "no-go" gage and some shim discs behind the gage, on the bolt face. It is pretty simple to remove the barrel and adjust the headspace to where the no-go would not go. You can surface grind a recoil lug or face some off of the shoulder. If more than a few thou, you might have to take the same amount from the end of the barrel and in the counterbore.
I've done this several times when swapping factory barrels on factory actions.

The reamer is speced @.468- to allow for the fact that the brass even for the 260 runs a little on the small side and that after reaming and polishing the chamber is just right.
You can make brass for your 250 from 243win brass and that will give you brass with the proper "size" for your chamber, which is "in spec" for the 250 Savage. The problem is most 250 Sav brass is way smaller than Sami specs.

All said and done, with a rifle shooting great, looking that good, treat it like a wildcat and make cases to fit. Enjoy your Remington.

Keep a close eye on the brass. Rifles with an out of round chamber can thin the brass in the web area if reloaded too many times. Take a paper clip and shape a small hook on one end. Use the end of the paper clip to feel for a groove forming on the inside of the case (in the web area). That can lead to a case head seperation. None of those in a lifetime is enough. One can be too many.

If you are going to handload, I wouldn't worry about the head space. Just size the case enough to set the shoulder back .001 or .002 thousands. then your cases will fit the chamber. could possible inprove the accuracy.
