I have seen ammo ads call out "boxer" or "berdan" primer. Are both non-corrosive? Is one better than the other?ThanksJeff

    Jeff -Boxer primers are the type used in modern American ammo. The anvil is integral to the primer and they are used in cases with a single, centered, flash hole. The design was conceived by a Brit.With the Berdan primer, developed by the Amreican, Hiram (?) Berdan, the anvil is part of the case and the flash holes (typically two, but in some cases 1 or 3) are offset toward the wall of the primer pocket. More difficult to reload, obviously, which is a large part of why the Boxer design was so popular here; the upper classes of the European nations had no need to save money or reload around a campfire. Some early US ammo have the Berdan system, but by 1880, it was pretty much out of use here. Both types are found in both corrosive and NC compositions, depending on age and manufacturer. The main reason for distinguishing between the priming system in listings / catalogs is that many Americans 'roll their own' and the usefulness of the fired cases for that purpose play a big role in purchase decisions.

    It's safe to assume that berdan primed surplus and commercial ammo is corrosive unless it is guaranteed to be noncorrosive. South African .223 military is advertized as having noncorrosive berdan priming.Some Norinco .223 and 7.62x39 was advertized as noncorrosive and wasn't.
