Welcome.

And, No. The 300 Norma has the larger case head diameter like the Lapua and Big Weatherby magnums. That size round really needs the lapua action.

On your action it is generally considered safe for any of the regular magnum sized bolt heads. 7mmRM, 300win, 375 Ruger, RUM, and the new Nosler line of magnums.

One hurdle is the bolt head.

Only the Lapua bolt head will work for the 300 Norma Mag.

Having a gunsmith open up the bolt head is not an option because it will leave not enough meat around the rim of the case.

There is another cartridge that is as good as the 300 Norma and doesn't need a Lapua size bolt head.... 30 Nosler !!!
