Remington Model 600 in 250-3000

I have acquired a Rem 600 in 250-3000. It's been customized with a beautiful piece of wood. I've tried to find out a bit about it on the Remington web site, but they claim they only made this Model in the following calibers: .222 Remington, .223 Remington, 6mm Remington, 6.5mm Remington, .308 Win, .35 Remington, .350 Remington Magnum. The "Remington Model 600" and the serial number, 902XX, are clearly stamped on the left hand side of the receiver; the caliber, "250-3000" is stamped on the lh side of the barrel. The barrel is 18 3/4 inchs long, and appears to be sleeved. Anyone out there have any idea what I've got? I'm thinking maybe, along with the stock work, somebody slapped a new barrel onto this old babe somewhere along the way.

Remington rarely claims that they only chambered certain rifles in certain cartridges without being able to account for this through their records. They have usually been very responsible in their effort to keep accurate records. I don't recall nor do any of my resources list a .250-3000 chambering in the M600 series.
Please look at the left side of your barrel as viewed from the butt. It should have a Remington Arms factory roll stamp and cartridge designation. If you check the right side, back by the intersection of the action and the barrel, you should see 'REP' in an oval. If you don't see either of these, you probably have an aftermarket barrel.
Remington did chamber the M700 Classic for the .250-3000 in 1984 so someone could have taken one of those barrels and fitted it to the M600. It would have required headspacing and timing. Then it would have both the roll marks and the chamber designation without it being an original factory combination.
Professional gunsmiths will not use a sleeve in an existing barrel if it is a high pressure centerfire cartridge.
An existing factory barrel could have been rebored and rifled to .25 caliber then chambered for the .250-3000 cartridge. Professional gunsmiths and barrel makers are supposed to remove the previous chamber designation and replace it with the new one.
An aftermarket barrel could have been treated in the same manner (rebored) so it would lack the Remington factory roll stamps and the cartridge designation should have been changed.
Best.
The only marking on the barrel is the caliber designation. I removed the stock to make sure nothing was tucked away, out of sight. So it appears that I have an aftermarket barrel with no maker mark at all. Interesting. Thank you very much for all the information you supplied to me! I know my "new" rifle a lot better now.
The guy I bought it from was shooting it at the local range, and was working with light weight bullets (87 and 95 grain). The groups were not impressive; 1 1/2 to 1 3/4 inch, at best, for three shots at 100 yards. He threw in some brass and a set of RCBS dies for it, so I can make it a winter project to see if I can get it shooting MOA.
In case you haven't done it yet, check the twist rate of your barrel as this will determine what weight (actually length) bullets you will be able to shoot best. Once you get the twist, you will also want to know the length of the chamber for the maximum seating depth. Granted the magazine length sets the maximum but with the .250-3000 there is some extra room in the magazine in case the chamber has a long throat.
If you get the chance, have the throat borescoped to see if it's got a carbon ring at the front of the throat as this is an evil thing when attempting to get any accuracy out of good loads. Then make sure the crown is concentric and perpendicular with the boreline. Give the barrel a thorough cleaning and start the load development.
Your short barrel will need some fairly fast powders so don't get locked into the standard powders that were tested in 24" barrels.
Enjoy the project and have fun!
Best.
Thanks again for another dose of information on the rifle! With your generous help, I just may be able to turn this pretty baby into a shooter!
