I'd just go with whatever your load recipe calls for, since some powders (like H110) greatly prefer a magnum primer to kick things off. If you're going to be using heavy loads of relatively slow powders, use a mag primer and crimp your bullets pretty good.
Yep. Your best bet is to use the primers your load manual calls for.;) Common usage is magnum primers for powders like W296/H110.
