Magnum Small Primers
Magnum primers are used mainly to ignite slower, hard to ignite, powders. Just follow the data you use. It’ll say if they used Magnum primers or not. Powders from Hodgdon will use them when the cartridge name includes the word “Magnum”
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.
