cci no 34 primer Overview
CCI 34 Primers (CCI 7.62mm NATO-Spec Military Primers) are a military large rifle primer containing magnum priming mix. The CCI #34 primers are a great choice for reloaders that use military cartridges. These primers are specially made to be harder to ignite which prevents slam fires in military type rifles with a floating firing pin. All CCI primers are continuously tested and improved. As a result today’s CCI primers are more sensitive, easier to seat and more compatible with progressive and automated loading equipment than ever before. They utilize modern non-corrosive and non-mercuric initiator mixes for the cleanest burn possible.

I use these in all my bolt guns with no problems. In comparing these with CCI 250’s the base of the primer cup to top of the anvil measures .125, the same as the 34’s. The cup thickness of the CCI 250 is .014 and the cup thickness of the 34 is .017. All measurement might be off by .001 but the relative distances apply. Can’t speak about hardness as reactions to firing pin strikes & pressure reaction appear to be the same. I keep in mind the label on the box – No. 34 PRIMERS For 7.62mm Ammunition, AKA .308 Win but for use in semi auto floating firing pin weapons. The 7.62/.308 is no magnum and some 7.62 ammo is loaded with extruded powders that don’t require magnum primers. I use in confidence and get good accuracy & no problems.
