I am new to reloading and wondering about something. I am currently useing federal 210 magnum primers , but when I was at my local gunshop yesterday I noticed they were out. How much difference is there in fed.210 and CCI mag. primers? Will it make any difference in my point of impact when I shoot my rifles?

Fed 210 are standard primers, the 215's are the magnums. You may have match primers, which are 210M. Changing a primer may or may not change your POI. Sorry, but that's the best answer there is short of actually using different primers to see. This chart may help:

Make sure you back off a little and work up, especially if you're loading near max.

Thanks for the info. By the way you are correct I have 215's. Guess it pays to go look rather than go on memory. Thanks again.
