3 Flash Holes? Doesn't appear to be drilled-out Berdan

Hello,

I'm relatively new to reloading rifle brass, though I've seen what 'normal' (2-hole) Berdan cases look like.

I often pick up other cases from my local range while policing my own (and TBH, I pick up un-collected brass as a hobby).

I came across a few 7.62x39 cases that have a ͶK 1982 ("Igman Factory at Konjic") that have 3 identical (small) flash holes arranged in a straight line.

Is this just a different version of Berdan primers? (I've heard of 3-hole Berdan's, though they were described as being arranged in a triangle).

Thanks all

Thank you guys.

Yes, I popped the primer out and it is, indeed, just a *very* pronounced anvil dimple.

Thanks again
