I'm about to put together some ammo for the 300 WM and would like to use RL22. The Nosler book calls for Federal 215 Primers. I believe those are magnum primers. I've never used mag primers while reloading for the 300 WM. Can I just use regular primers?

I've got a bunch of regular primers and don't want to spend the gas money to drive around looking for mag primers.

Thanks

Tom
