300wm box magazine.

Can my magazine be used with the 300 Norma cartridge?

I predict NO. The 300 Norma case is too fat.

Possible you might get it to hold and feed 2 if stagger feed and you are really good at tuning mag lips.

Bolt issue too

Yep, but he didn't ask about that.

Compatibility is "designed in" with the .300 PRC cartridge. Probably a better choice.

COAL may be an issue as well. With the exception of Remington 700's and it's clones as well as the Sako 75/85, most 300WinMag boxes are set up for 3.34" COAL.

Thanks for advise. Answers accepted as no. Since my last post I decided not to build a long range 300 Norma but to purchase a MasterPiece Arms rifle in the same caliber. Wait time is about as long on components as a ready made rifle. Did opt for my own timney trigger and precision arms gen 3 bastard brake. Have dies coming and eventually will find H1000 powder and match primers. New rifle due in September.
