Does primer sealing really matter (.223/5.56)?

    I notice most of the Hornady loads (with the exception of the impossible-to-find 75gr 5.56) do not have sealed primers. Does it really matter?

    Depends. In an environment with high humidity, or where you and your ammo are more likely to encounter wet, muddy, humid, or otherwise nasty problems, it is a cheap insurance policy to have sealed case mouth and primer. If your ammo spends 99% of its life inside your air conditioned home, and is intended for HD duty, it's probably not that big of a deal.
