So, a buddy at work today asked me about rat shot rounds. They are for his father who mows a lot of property and finds rattlesnakes too often. I vaguely remember people talking about that a couple of years ago. Yes, they don't cycle semi-autos. Yes, I've seen the roll-your-owns with #9's. Yes, CCI makes some. I'm thinking about a .38/.357 mag revolver for him. Anybody had any experience loading for them?
