Thanks so much, I kind of assumed all these answers, but wasn't positive. I had a cop tell me yesterday after I asked him what if my car burglar alarm goes off at 2 in the morning, what can I do, he said the same thing, call 911.
I immediately told him that the thieves would be gone before the 911 call is even answered, he agreed and had no solutions, except to remind me that the use of deadly force outside your home for property theft is not legal. He told me I could yell at them lol.
Back in the day when I was young, a lot of the farmers would use shotguns and rock salt to scare off the kids or thieves that were stealing whatever, I think I even had a friend that was hit with some, hurt like hell but didn't Mame or kill him.
I would think that replacing lead with rock salt would not be dangerous as far as reloading with the same load, the rock salt has to be lighter than lead, thus reducing the pressure quite a bit.
