I have read the CCI 34 primers are magnum primers.Are they hot enough for 300 Norma?or should I get regular Magnum primers?I have 5000 of the CCI 34.
 
They do have a heavy cup, so they'd stand up to the pressure. I tried some br-2's (also thick cup) in a 338 lapua not long ago. Worked fine. Load was about 5fps slower than the same load with Fed 215m's.

My guess is it would work fine.
