Model 70 Winchester pre-WWII has 300MAG as the caliber. My question is what 300Mag?

I didn't think Winchester had a model 70 Rifle 300MAG that early or that the Winchester 300mag was available that early. Was there another 300 mag chambering for the Model 70?

The only .300 Magnum that existed before WWII was the .300 H&H Magnum.

introduced as a cartridge in 1925, and chambered in the Win M70 in 1937.

The next .300 Magnum in the Model 70 was the .300 Winchester magnum introduced in 1963.

Pretty hard to find a pre-war ANYTHING in 222 Remington. The 222 Remington cartridge was developed in 1950, 5 years after WW2.

There were some Hornets converted to .222. The quickie conversion was a rechamber and bolt face job, there were a few deluxe rifles with working magazines.

How sure are you the barrel is original?
Bought a 1952 vintage compilation of Jack O'Connor's articles while being couped up by the Covid Panic. .300 Mag meant .300 H&H or .300 Weatherby in 1952. The Weatherby came along in 1944.
