Here I am firing.

You can see the hasp of the lock in the air on the right side of the picture.

And this is the result, a broken lock.

Notice the line of "splash" that we got from where the powder hit the top of the lock

It cut a groove in the wood behind the lock as marked by the arrows.

I am pulling out part of the shot cup that was imbedded in the wood.

Well, they worked on a lock, just as advertised.

So, the next question is, "Are they safer to use indoors and will they penetrate drywall walls?"

I set up the old "Box O' Truth" with 12 sheets of 5/8 drywall in it.

Here I am, shooting it with a breaching round.

As often happens at 15 feet, the wadding made a second hole in the first sheet of drywall.
