I have 2 boxes of Winchester Super X 358 caliber, 200 grain, Silvertip EXP shells. If I remember correctly these are probably reloads in the winchester boxes. These are 30 years old or more. Boxes are in great shape and shells look new!! $50 per box. If you take both boxes I'll include 10 loose shells 8 of which look like they would be the original silvertips. Probably some empty cases around too !!
