Word out there is CCI 34s are getting hard to come by. I paid $35 for a brick last week and hated doing it, but they are out of stock usually locally. I've never seen Russian primers for sale locally/ Supposedly the ones mentioned abover are excellent from a consistency standpoint (some high power 1000 yard match guys like them).
CCI mag rifle primers are supposedly pretty close in slam fire resistance. Federal supposed to be the worst? I've shot Fed, Fed Match, WLR, WLRM, CCI standard, CCI mag, etc. in my Garands, and they have all had striker dents in them when I eject live rounds and have never had a slam fire.
