Running CCI Mag. 250's in my .243win

Bamapse

I was given 1k CCI Magnum rifle 250's for Christmas and was wondering if I can run them in my .243win. I have been running crappy winchesters and wanted to switch but wasn't sure about the 250's. If so, do I need to adjust my powder charge since it should burn faster? Thanks in advance!
 
They will burn hotter. If they are anything like Federal 215Ms, you will need to back off .5 grains and possibly a bit more than that.
 
+1 on that.They are a good primer.I run them in everything when I can get them.
