Our local law enforcement has been at the range in force, burning up "tactical" ammo.
One of the leftovers is some light blue 12 ga hulls which originally held a slug and apparently had a roll crimp. These hulls are shorter than 2 3/4" and probably only suitable for slugs and roll crimps. They are marked Federal Premium and are almost surely basically Federal Gold Medal.
If anybody needs 25 or so, PM me... yours for the price of postage.
