CCI Muzzleloading Primers are specifically produced for the Inline Muzzleloading hunter. is continuously testing and improving their primers and as a result, their primers are more sensitive, easier to seat, and more compatible with today’s inline muzzleloading rifles. These primers utilize modern non-corrosive and non-mercuric initiator mixes for the cleanest burn possible. One of the benefits of using primers specifically designed for muzzleloading rifles is that they are milder than regular 209 shotshell primers meaning they do not force the powder charge forward helping to maintain consistent velocities and they help to minimize the formation of crud rings. These primers are not designed to be used in shotshells, they are for muzzleloading rifles only
Darren, the sole purpose of a primer is to ignite the gun powder. Therefore the Brisance rating is of no practical use to you. Unless you are constructing your loads at maximum powder capacity. The only way that I know would be to set up some loads with different primer brands and chronograph them to see if velocity changes dramatically. And to visually Inspect your casings for signs of overpressure. Of course, this would only be valid for that lot # of primers. All of the different manufacturers’ primers will have different amounts of flash due to proprietary ingredients in their manufacturing. Magnum primers contain more compounds than standard primers. If you use magnum primers in standard loads reduce your powder amount by 10%. Hope this helped.
