300 mag is much bigger bullet
Value of a weatherby .300 magnum made in germany
Rifle chambered in one of the cartridges named Winchester Magnum- such as the .300 Winchester Magnum- or .300 Win mag for short.
None. the term "300 Weatherby Magnum" is not merely a brand, it IS the caliber of the cartridge (no matter who makes it) It does NOT interchange with the .300 Winchester Magnum cartridge.
7mm Magnum and 300 Winchester Magnum
There was no 300 Winchester Magnum cartridge in 1939. A 1939 Model 70 would be marked "300 Mag"...and it will be chambered for the 300 H&H Magnum cartridge. There was no other 30 Magnum cartridge in 1939 in the Model 70. The 300 Winchester magnum cartridge was introduced in 1963,...the last year the Pre'64 Model 70 was made. Your 1939 Model 70 may have had a later barrel swapped in to it. 300 Winchester and 300 Win Mag are the same cartridge.
300 or so
404 Jeffreys

No. The WSM stands for Winchester Short Magnum. They are not interchangeable.
The 300 Win Mag wasn't introduced until 1963. It could have had a new barrel put on it. Take it to a gunsmith.
NOTHING............Its a Remington
