If I can find some, what can I expect or not expect from such cartridges? I'm figuring this might be a decent snake/varminter rounds for the camp this summer. Here in MA, we can't buy ammo thru catalog, so I'll probably have to order it thru a dealer. I am not even sure if they make shot loads in .357 Mag. caliber? Do they come in various loads, or just one loading per caliber. Thanks folks.
