IK 07 is on the headstamp red primer sealant. Found a bunch in the desert, boxer primed, but boy are those primers tough to get out. broke/bent 2 decapping pins on 3 pieces of brass. ordered a depriming punch

Headstamps can be found here:

I use a universal decapping die for everything, but it is especially useful on military brass.

Probably Igman Zavod, Konjic Yugoslavia

hey man the primers are crimped in.so if it was me I would leave them a lone.

The IK brass I have reloaded does seem to break more decapping pins then any other .223 brass.

I don't know if the primers have more of a crimp or not. After a trip through the super swage they give me no more trouble.

Crimped primers are not a problem. You can easily deprime with the RCBS Heavy Duty Depriming Dies. Then you need to swage the crimp or remove it with a pocket knife/drill/your favorite method. You do this only once and the brass is good forever after.

If you are breaking a lot of pins, the brass may very well be berdan primed. Shine a light into the case and see if you see one or two holes in the bottom. Two holes is BERDAN and this brass should be consigned to the scrap bucket.

Heretic is right. ---AND---- Yugoslav brass may certainly be primed with berdan primes as medalguy mentioned
