There is one at a local shop here in town and if my memory serves me correctly the barrel says 257 Rob and then back towards the chamber it says 257 Mag or 257 Win Mag, I don't remember exactly ill swing by and take a photo when I go to town. Anyone seen or heard of this? The price tag says 257 Weatherby Mag, and it is $ 1299 before you ask lol, which I think is a fair price.

If its a 257 Weatherby it's not the original barrel. No such thing as a 257 Win Mag. It's either an original 257 Roberts or a rifle that has been modified for a 257 Weatherby.

If it says 257 Roberts and 257 Weatherby on the barrel, I would not buy it. That would likely mean that someone rechambered a 257 Roberts barrel to 257 Weatherby. This would require modifications to the bolt face and receiver which destroys the value of a pre 64 M70.

You sure it’s not a 264 win mag?

.257 Roberts was one of the original chamberings. Yea, you need to determine if the gun is original. If not it's not worthless as a shooter... If all original and in good condition it would be a collector.

264 Winchester magnum was introduced in 1957 or 1958. If it's really a 1952 M70 it predates that cartridge by a few years.

Since the op couldn’t remember the chambering, I didn’t really put much stock in the gun being a 1952 model and 264 win mag just seemed to fit better.

Legit reasoning

Matt not to pick on you but let's all cuss whomever rechambered a Bob to Weatherby.

It's more likely a 92 M70 than a 52 😁

That's a shame, Pre-64 Model 70's in 257 Roberts are hard to find and someone ruined it by rechambering to 257 Mag. It's not worth $1299, maybe half that. I'd leave it since I doubt you'd be able to shoot it first before you buy.

It's not worth half the price they're asking for it. To modify a 257 Bob to 257 Roy, the bolt face would have too be milled for a larger case head or the bolt was swapped with a magnum bolt, which means the serial numbers don't match. Either if these will devalue the gun. Also may have feeding issues unless a gunsmith modified the feed rails and follower, which also devalues the gun.

I wouldn't give $400 for that gun.

Well that's unfortunate 😕.

But the question remains; was it manufactured in 1952?

I looked it up, shows 1953

Not only is that dumb as shit its dangerous to leave 2 different chamberings listed on the barrel. I'd like to take a rubber hose to both the owner and the Smith that did that

Just curious but is this at bluegrass and bullets?

Nah
