I've noticed some Super Vel .357 Mag popping up as I've cleaned cases and reloaded. I continually find .357 mag brass from when I first started shooting 35 yrs ago, in a coffee can in the basement or garage, an old box full of "stuff" in the barn. I have no idea when or where I got it but I've quarantined those cases (about a box of 50).
May trade them for something if I find someone has an interest. Interesting to read the stories.
