If you are reffering to a Winchester model 70 bolt action rifle chambered in 257 roberts,then your serial number indicates that your model 70 rifle was made in the year 1950.
Quite a few different ones. Some of the more notorious ones were war souvenir Japanese Arisaka rifles, which had been converted to fire the .257 Roberts, as the Japanese ammunition was a bit scarce on the commercial market. I know the Ruger rifles were made available in .257 Roberts, including the Mk. II and M77, as were the Winchester Model 70, Browning Model 81, and Remington 700. Sako made custom rifles in that calibre, as well.
100-1000 USD depending on specifics. Try proofhouse for the sn.
Most of these rifles will range in price from 375-475 dollars depending on overall condition,and a good bore.There will be a premium if the rifle is chambered in a more unusual caliber(257 roberts,7mm Mauser etc.)
Actually your Winchester model 70 bolt action rifle was made in the year 1937,which makes it a pre-war model 70.This was the first year Winchester ramped up production and made 9334 model 70 rifles.A pre-war model 70 rifle in .257 Roberts will bring between 775-1,850 dollars for a rifle showing between 60%-90% of it,s original finish,and a receiver that has not been drilled and tapped for a scope mount.If by chance that you have a super grade model 70 you can add 100% to the above listed values.All pre-war model 70 rifles should have only 2 holes drilled in the front of the receiver(none in the back) A extra set of holes will decrease the value by 50%.If your serial number has a Letter D suffix indicating a doubled up serial number;this variation will command a premium because of it,s rarity.
Based on an exhaustive Google search, I don't believe so. They did make a .257 Roberts, at least in 1942, and it is rare. Sometimes these were reamed out later by gunsmiths to .257 Weatherby Magnum, and the barrel markings may or may not have been changed.
The dry weight of the 1985 model, 70 hp Evinrude outboard is 257 lbs.
Winchester makes the Model 70
It is a long action that has limiting spacers included. The magazine has a spacer at the rear and the bolt has a different bolt stop that prevents the bolt from moving to the full long action length. So I have been told.
