300-700 USD
300 mag is much bigger bullet
A Sears Model 300 Winchester Mag rifle could actually be worth several thousand dollars. A rifle in very good condition can sell for up $3,500.
300-1000 USD what if the gun is pre 1964
Yes
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.
Yes--I have a friend who has a 721 chambered for 300 super mag
Both are .30 caliber.
