.300 WM Large primers or Magnums

[jrcarbine]

I'm starting to reload my .300 Win mag. I'm not sure what primers to use in it. Do I use the Large rifle primers or the Magnum primers? why?

It's not a bad idea to use the Magnum primers in a case as large as the 300 Win Mag.

I usually use them as soon as I get over 60 grains of powder to ignite.
More reliable ignition, particularly with spherical powders or in very cold weather.

Regards, Dave.

I bet you can't find a published reloading manual with pressure tested data that uses anything other than magnum primers in magnum cartridges. Since you are just starting, why try to re-invent the wheel?

Agreed!

Go with what the load manual states, which will probably be magnum.

I use only magnum primers in the 300wm.

Alright thanks for the advice guys.
