I don't know if this is a Massachusetts thing, but I was curious if anyone has any experience with this ammo. I just picked up a half case (for really cheap) of 158gr and 148gr wad cutters. It looks to be commercially reloaded nickel cased (Western, Peters, R-P, etc...) ammo manufactured in the 60's (give or take a decade). The boxes are a very utilitarian green and white and they are marked "manufactured in Tewksbury, Mass".
