I've been gifted with a large cigar box full of like new loose but mixed head stamp 32-20 ammo. I've also been warned about using rifle ammo in a revolver. I have an as new S&W hand ejector and a Uberti single action both are 32-20. None of this ammo is jacketed or hollow point. I have sorted & I would say it looks like 4 groups. One is starline head stamp, which I expect is cowboy action stuff. The rest is WW headstamp. One is with brass colored primers, one with silver color primers & the last group is still WW with silver primers but there is a red colored sealant looking material around the primers. Again, except for the starline, the rest is WW & all projectiles are plain lead. Do we have any ammo experts? THANKS!
