Dave, somewhere in the past couple of weeks I read that one of the European slug loads hits 1900 FPS. The buckshot load (IIRC) has three 000 pellets. Have no desire to stand in front of a .410, even loaded with breath mints....
Mark Morowitz once penned that the first rule of a gunfight is to have a gun....... All other rules are way down the chart, but IMHO rule #2 is have a reliable one.
