Sorry for the kinda novice question... I have only been reloading for my Savage 300 WM and I have used CCI 250's with those. For my new rifle, I just read from Hornady 300 PRC load data they suggest Federal 215. https://www.hornady.com/assets/site/hornady/files/load-data/300-prc-v2.pdf
Why? What the difference in Primers?
