Anyone use cci 450 primers in the 223 AI or is this primer too hot for the 223? I have quite a few on hand, but am running low on cci 400 and fed 205. Since the 450's are hotter, would I need to load down on the powder charge? Thanks in advance. Just trying to make due with what I've got and still keep the 223 AI up and running. By the way, this is in a bolt gun.
