NOTE: Weatherby did produce a small run of non-Weatherby caliber ammunition in 1997. Calibers included: .270 Win., .30-06 Spfd., 7mm Rem. Mag., .300 Win. Mag., .338 Win. Mag., and .375 H&H Mag.

If your gun was made around this time, I't might be a Win Mag.
If it was not, your gun is chambered for 300 Weatherby Mag.

Pretty sure that it's a weatherby mag. But I have seen them in win mag. A win mag will chamber in it but will be loose. I believe the weatherby mag is a little longer and a little larger in diameter. I would take it to a gunsmith.

Seems like the Vangards were in the more common calibers. Being the longest,If the Weatherby round will chamber, that's it.

The Wby case is a little longer but has the same rim and head diameter. Both should chamber in the Wby chamber but only the Winny will chamber in the Winny chamber.

HOWEVER.....................

The smart thing to do is take it to a good gunsmith and have him check it. If it is chambered in something funky there could be disasterous results when you pull the trigger with the wrong ammo.

Be sure BEFORE someone pulls the trigger. Mark Vs were much more common in .300 WEA (Weatherby mag) but have also been produced in .300 Win Mag. As this is marked .300 WM, a .300 Win Mag is what it SHOULD be. With that marking I would be 99.9% sure it's a .300 Win Mag.

If a .300 Weatherby round will fit in the chamber, it is a .300 weatherby chamber as the .300 WM is a little smaller. A .300 WM will fit in either chamber.

Hope this helps.
