I just haven't got round to painting, I just have a fired projectile in. The one Cinders shows is just a standard tracer and I never saw those. The one Muffet shows is the one I saw. Two color like the UKissue observing ammo issued for .50 cal. We shot lots of those in the M2s for night shoots. I don't know how much of a smash it would take to set off on in your basement but I wouldn't want to find out either.
