Default Standard or Magnum primers?

When loading the 300 Win Mag and the 300 Rem SAUM, should I use the magnum or standard primer? What are the advantages of using magnum and what are the cons of using standard?

I would use the Magnum primers. The mag primers will give you a more consistant ignition when using large amounts of slow burning extruded powder in magnum cartridges.

Thanks for the replies. Will changing to magnum primers increase speed, change point of impact or have any other effects?

You should always follow the directions of your loading manual.....I can't believe that there's a loading manual anywhere that recommends a standard rifle primer in a .300 Win Mag case!!!

I was just looking at the Hodgons reloading manual #25 edition
every magnum 7mm through 460 weatherby (PRIMER SIZE) LARGE RIFLE
(quotes)Some powders need mag primers but doesn't say which ones.

Hunter40, I have the Hodgdon's #26 manual......and it says "large rifle primer" for the .300 Mag and others as well!!!

From personal experience, there's little difference between Large rifle and magnum primers!!!
