The Federal 215 is the hottest magnum primer made, followed by Winchester Mag rifle. Both are excellent in large volume cases with 70 grains or more of powder. They are the only two that will consistently ignite these large charges.
I use CCI 250 mag primers in all of my hunting loads 243 to 45-70 and Fed 215 or Win Mag in all my magnum loads 7 Rem Mag to 460 Weatherby. The CCI 250 are good insurance for cold weather hunting. They burn hotter and longer than non mag. Non mag will work fine for target or summer guns and are what most people use even in their hunting rifles for winter loads. They work, its just I like the extra insurance.
