My dad was given about 2,000 CCI 450 "magnum" primers by a friend who got out of reloading. Since my dad doesn't reload for small rifle he passed them along to me.

So my question is what is the difference between these two primers? None of my reloading data even lists these primers with .223/5.56 loads. Why can't they be used with other powders?

As safety is rule #1 I am not planning on using them, just curious as to the difference and wondering where I can use them.

Thanks
