I am still lost how you get OE to look anything like what's in your case, but regardless, your cartridge is darn interesting.
Personally, I would bet that you pulled the bullet out with your fingers. One does not roll crimp paper patches. Might taper crimp them slightly but that's all. Target cartridges often fall out of the case if inverted. Double guns will require a little resistence to deal with recoil and especially handling in the field. Taper crimping with dedicated die or by removing the core from a FL sizing die and touching it fairly gently gets the job done.
I think I'll pull another one of my cartridges and photo the powder to post it here. Yes, it does, most certainly, ignite. And with plenty of vigor. BP has basically no shelf life limitations if keep at reasonable temperatures.
