These rounds have many names, snake loads, rat shot but they are typically sold as Shot Shells. As a heads up. Most semi-auto pistols will not cycle these rounds. They work well in revolvers. My semi-auto pistol will not cycle them but my wife's little semi-auto will. In the larger caliper 357, 41 mag and 44 mag, these rounds are very effective on small critters. Years ago, I sent several snakes to the happy snake playground with my 357 shot shells.
