I'd hang onto any S&W ammo as a collectible. At least, the old stuff from the 70s and 80s. Don't often see it anymore.
It was good ammo in its day. I recall using some 158 gr. jacketed hollowpoint stuff in my Ruger Security Six in the early 1980s. It really bucked and bellowed but was accurate.
Alas, that box is long gone. Wish I'd at least kept the empty box as a decorator.
