Need help with ID 5,56x45 Dummy


#1

What the M-numbers of dummy cartridges №№2 and 3. What does the brown (or black?) color on the primer number 3?

Regards

I think no.2 is also designated M232.
The dark coloured primers usually indicate an inert primer. I’m not sure about no.3 but the black primer and lack of crimping would suggest to me that this could be a cook-off test round. You could pull the bullet to see what, if anything, is inside. If it contains propellant then it’ll be a cook-off test round. It’s certainly unusual to see a dummy round with so little crimping.

Have you looked at the free list Ron Fuchs has available for download?
