Help what best primers for 300 wsm and can i use large rifle primers like cci large rifle br-2 thank for help

I use magnum large rifle primers in mine. I think this amount of powder warrants use of the magnum primer vs the standard large rifle primer. I've used both WLRM and Fed 215M. I prefer the Federals, but that is personal preference only. The Winchesters worked fine as well.

I only use Federal primers, 210M and 215M in my loads. I use the Winchester primers in my brother's ammo. I would use the magnum primer in your 300
