That's what I remember from taking them apart. The primer seemed to be a dried green crust down in there. Forty years ago I survived the task of scraping it out of a bunch of cases, and the resulting powder, along with the gunpowder, guts from a bunch of small firecrackers, and some crunched up match heads, inside one of those little Bayer aspirin tins, bound up by an entire roll of masking tape, made an interesting device to light and toss out the dorm window, for sure.
(Also prepared a batch of ammonium iodide, which was a blast [pun intended]! The best one, for the show of it, was a small oil can full of equal parts, IIRC, sugar and saltpeter, with contact wires to a broken flash bulb imbedded therein with its filament exposed, and the spout of crimped to hold the wires. The entire device disappeared, and some of the guys in the dining hall reported the entire woods lit up momentarily by the flash, opposite the big room's wall of windows. No one hurt, nothing damaged, fortunately. Amazing how the young mind amuses itself...)
