Sorting thru a box of junk US Military, one caught my eye.
Dummy, Tinned Brass, RA 17, Six flutes and 3 holes, CN bullet. Odd part is that it’s primed and the primer has a D stamped on it. (Makes me wonder how that primer has survived 92 years without someone pulling the trigger on it)
I seem to remember these marked primers being discussed before but don’t know how I could search for a thread without getting hundreds of hits.
So, save me time. What is it?
