Boxer primed is std. US made ammo. It has only ONE flash hole on the inside center of the spent case.
The Berdan primed ammo, mostly foreign military ammo, has 2 smaller flash holes that are NOT centered. Thus your std reloading depriming die will not work.
Hope this helps.

I was wondering if you can tell on loaded ammunition,But firing one and inspecting it works also.
Thank You

IIRC, the diameters are different. With a good eye and a set of
calipers you should be able to determine primer type from
loaded ammo.
