Ok... havent ran into this yet... but wanted to know.

 

A Bunch of Makarov ammo made by wolf and brown bear is berdan primed... what the heck is it?

It has a lip, it is crimped in for machine gun use.

Bredan priming is used mostly in overseas. It has a double flash hole instead of the single center hole flashhider like boxer primed ammo.

 

A small copper cylinder formed the shell of the cartridge, and the primer cap was pressed into a recess in the outside of the closed end of the cartridge opposite the bullet. In the end of the cartridge beneath the primer cap was a small vent-hole, as well as a small teat-like projection or point (later to be known as an anvil) fashioned from the case, such that the firing pin could crush the primer against the anvil and ignite the propellant.

My understanding is that berdan primers are a diffrent size than rifle primers and should not be substituded for one another, you should remove the berdan primer with the appropriate tool and replace it with another berdan primer.

You can reload berdan primed brass if you can find the primers. You can also convert berdan primed brass to boxer primers but it is a lot of work. I think either option I've l;isted just isn't worth it.
