    Check out the pressure differences in primers!

    Here’s some interesting ballistic pressure data comparing Fiocchi Magnum 616, standard Fiocchi 616, and Federal 209A.

    Looks like the Fio Mag 616 are hotter than Fed 209A in this tested data.

    Interesting!

    A good read here too if you haven't seen it:

    A primer change can make quite a difference just between brands! All 209 primers are not created equal!

    Price between brands can be a lot different too. I’ve always stayed in the mid price range, but have recently been considering the more economical brands, since I’m mostly plinking these days. However, for those who really want to get zeroed in, I’m sure experimenting with different brands can make can make a difference. If you can find them these days!
