Home Forums Hunting & Shooting AR and Tactical Rifles Large Rifle Primers For AR10, FAL,M1A?

I've read enough here and elsewhere that I think I have a handle on which primers are safe in an AR15; what about large rifle primers for similar rifles in .308, 6.5 CM etc? Obviously CCI 34 would be best, but I'm out and there are none to be had.

My specific problem presently is what to use in some .308's for a FAL, I have CCI 250's, Sellier and Bellots and recent production WLRM's that are likely candidates. Any of those I should avoid? Would prefer to use the Winchesters because I have brass already primed with them, but that is merely a timesaver.

Thanks in advance.
