Home Forums Hunting & Shooting Winchester Collectors a winchester bullet inside a bullet? what is this?

It's a Winchester "Supplemental Chamber". Can't tell if this one is .30-30, .30-40, or .32 WS. WW made them for indoor/gallery use. Most likely it will accept a .32 S&W (the original short version) or .32 Colt (if a .32).

Neat find. No idea on value.
