Which magnum large rifle primer has the most go/brisiance/flame?

I'm currently loading 143grns of powder with Federal 215 primer in my 416 and was wondering if there was a primer with more oomgh to try out.

Just playing around.

I think the Winchester WLRM is the "hottest" and the Fed 215 or CCI are next. I use Win primers more than any other.
Are you trying to address a problem or just playing with it?
