I thought standard CCI's were a "mild" primer close to Win 209's. I think CCI makes two, a standard 209 and "Magnum" 209, the CCI 209M. Fed 209A's are considered a "magnum" or hot primer as well and raise pressures in most loadings. I am pretty sure I read somewhere that Federal came out with an even hotter primer. If my recall is correct Remington 209P is about the mildest of primers.
I think the best way to tell is to go into the reloading recipes in the on-line Alliant manual or Hodgdon and look at loads where all things are equal except the primer choice.
