I have 200-300 rounds of Devastators (detonating tip) and Glaser safety slugs, in a variety of calibers -- 45, 9mm, 38 special, 357 mag, 25. They are all new old stock in original, unopened retail packaging.
You better check the legality of owning them. Some states have banned those types of ammo from private ownership. When i was still with LEA in CO. in the early 80s glasers were illegal for private citizens to own.
