I don't use it for serious purposes, but I do keep a box on hand(as well as a couple more to see what they perform like in whatever shotgun they're feeding)-lately my Remington 870 and Spartan semiauto, both 00 in a 3 1/2 inch load. A few years ago, a video store in the town I was then living in was robbed, perp ended up shooting a deputy one town away(deputy survived but has 115 grains of lead in his shoulder to this day) and doubled back on foot back to our town, where he was caught the next day. Later we found signs that he spent some time in our backyard, possibly overnight in the garage. After that I like to have something heavy on-hand even if I don't actually keep anything loaded.
