I will start my answer with a question?Are you sure that your winchester model 70 was made by winchester in 1948?I ask this because the 300 win.magnum was not a chambering that was available until the late 1950,s.The cartridge was based on a 458 winchester magnum case that was necked down.The 458 winchester came into being in 1956-1958.It also spawned the 264 win.mag caliber,and the .338 win mag caliber.I would expect that your winchester model 70 rifle was rechambered at some point in time if it is indeed a winchester model 70 made in 1948.This can also be said if we are talking about the .300 weatherby mag chambering.
Your rifle is worth alot it is pre 1964 a 1948 model to be exact I would get a professional involved.The 264 was an awsome cal. It was known to be a little hard on barrels.Good luck!!
