I've got Fed 215's and CCI 250's. I've run the 215's in 300 and 338 Win. I have a little 7828 and RL-22 left, but I'll mostly be burning IMR-4350 to H-4831 type powders.

In my 264 I use winchester mag primers, I use win mag primers when I use powders that burn slower than H4831, with faster burning powders like IMR 4350 the Cci 250 primers are fine.
