Q: How do No. 34 large rifle primers from CCI differ from the standard large rifle type?
A: According to sources at CCI, the No. 34 primer is constructed to reduce or eliminate the possibility of slam fires in service rifles or other self-loaders. This is accomplished by utilizing a harder cup and more anvil clearance. The No. 34 is not designated as a magnum primer. It should be usable in any firearm type with a sound ignition system; the pressure generated should not be any greater than that produced by the company’s standard primer.
