    Primer differences - Does it really matter?

    I've been using Federal Premium Large Rifle primers in my Rem Sendero 7mm Magnum with amazing results working through load development. I'm getting 3042fps velocity and 0.38 MOA off the bipod. The gun I believe can achieve better. It's me that's holding back a better MOA
    Then I learn you can get "Magnum" primers.
    Then I learn "Match" are even better
    I hear that they all come off the same run anyway, just when the machine is running smoothly they put those ones aside and label them Match primers.
    Should I be using Magnum? If so why? What's the difference?
    If I change to Magnum and/or Match will it affect my load development/POI at all?
