I'm not a novice handloader but not an expert either. I'm planning to work up some new loads for my 7mm Rem Mag and my new Kimber 7mm-08 and found myself wondering about primers.
My question is this: Is there much difference in primers? That is to say will it make noticeable difference whether one uses Fed 215, Rem 9 1/2M, or CCI 250 primers in a magnum rifle load, or Fed 210, Rem 9 1/2, or CCI 200 primers in a large rifle load? Looking through the reloading manuals the primer choice seems fairly random beyond using magnum primers for magnum loads, etc. Am I missing something?
If so, is there some logic, science, or rule of thumb in how to choose a brand of primer for a given case/load?
Is there ever reason to use a magnum primer in a non-magnum cartridge, or vice-versa?
I'm not a competition rifle shooter, but I'm a technical tinkerer and would love to learn more. Thanks in advance!
