Number 41 Mil-spec primers are manufactured to the same standards as the U.S. military and lessen the likelihood of a slam fire. They use the same data as CCI magnum primers, while being developed for semi-automatic rifles of a military design.

Note from CCI:

• Effective slam-fire prevention requires more than mil-spec primers. Headspace, chamber condition, firing pin shape and protrusion, bolt velocity, case condition and other factors can affect slam-fire potential.
