In tactical use, the shotgun slug serves as the heavy hitter for civilian duties.
A one-ounce rifled slug at 1560 fps = 2375 ft. lbs of energy from an approximately 70-caliber projectile.
A 3/4 ounce Barnes-expander slug from a 3" 12 gauge can deliver up to 2600 foot pounds.
So what would it be used for?
- Vehicle disabling shots
- Hitting occupants inside a vehicle
- Firing at barricaded hostiles (firing thru some barricades)
- Firing through exterior walls (i.e. next to or below windows)
- Door breeching (destroys door lockworks on contact)
- Use against hostiles with body armor (if it doesn't penetrate, it hurts like hell!)
- Firing through walls - sheetrock, plaster, plywood
- Firing through furniture - sofas, beds, dressers, tables
In short, any time you need lots of penetration to reach a hostile target, you can call on the shotgun slug. Even the 20-gauge can deliver 2,000 ft-lbs of energy from a slug.
Using a 12-bore slug against an unarmored person will generally take the starch out of his shorts -- all the way to his socks. Even drug-induced psychos tend to become anchored to the sidewalk when solidly hit with a big slug.
If a Major League pitcher threw a fast-ball into your stomach at home plate... consider that as a .45 ACP hit. When you've recovered and stand up again, being run over by a charging 1800 pound Buffalo is the receiving end of a slug.
