On our unit we use Hatton rounds in our breaching shotguns (cut down Remington 870's). It's a simple solid slug round, which is very effective at not only destroying locks but also disabling vehicle wheels. On each team, one man will be designated the "Hatton Man". His job is just to do all Method Of Entry functions and he will carry just a shotgun loaded with Hatton rounds and a pistol. If we do a hard stop operation on offenders in vehicles, the Hatton Man will stand near one of the vehicle's wheels, and if the vehicle moves at all he will put a Hatton round straight through the wheel.
Simple and very effective!
