Anyone using Federal mag rifle primers? I have access to buy some wondering how they match up to CCI magnum primers? Are they any hotter ? will they affect the bullestics if using CCI magnum primers? Any help would be appreciated!

215's are hotter than CCI 250's and Win Mag is the very hottest by far.

I use all three in different loads. In my large guns, when the primer pockets get loose with the 215's, the Win Mag will be very tight, but will require a slight variation in the load.

I use both Win LR Mags and Federal 215s in my 45-70 BP loads. They both light up the BP just fine. Never got around to trying out the CCIs, so can't make a comparison.

i use both .in 270, 7mm, 375 h&h from africa 100dgs to canada-15 dgs cant tell any change

In buring hottnes as follows:

CCI 250 Coolest
Fed 215
Winchester Magnum Hottest of all.

In my experience, the Fed 215 is quite a bit hotter than the CCI 250, work up your loads accordingly.

Thanks for the info - where did you find a list of 'hotness' for primers? I've always wondered about that.

CRounds, friend did a lot of R and D for many of the gunmakers and ammo makers around the world. I verified this in my own experience. My friend actually took pictures of the primers at ignition, took pictures and published them in Precision Shooting Magazine.
