Lessons learned:
1. At 20 yards, you might scare a dog or some other animal, but you sure wouldn't break the skin.
2. At 10 yards, you might break the skin with a couple of grains, but nothing very serious.
3. At 12 feet, you might get the desired effect, if the desired effect is to "burn" the target with the rock salt.
4. At 4 feet, you might cause a wound requiring a visit to a hospital for a human, or maybe death to a small animal.
5. Movie plots that show someone "burning" a bad guy at across-the-yard distances are hogwash.
6. Rock salt makes a pitiful personal defense load, as if we didn't already know that.
Got home and broke out the Tampax and soapy water, and got to work cleaning the barrel of the shotgun. I'm not going to take the chance of leaving salt deposits in the barrel.
I then ran very hot water through the barrel and dried it completely. Then cleaned and oiled it as normal.
I then returned the plated 00 Buckshot to the magazine. If I ever have to "burn" a bad guy, he's not going to have any doubts or complaints about lack of penetration.
Shooting stuff is fun, even if it is something as silly as rock salt loads in a shotgun.smilie
Dimes don't work either
ROCK SALT, not table salt, is a non-lethal projectile. Unless, like mooncoon says, it get wet and turns into a slug. Of course, if you use it on anybody or anything, you'll be arrested.
Gonna try those little hard shiny cake decorating beads in my shotgun one day. They will break your teeth and are mostly sugar I think. Pop a grouse under 10yds - no lead or steel in the meat. I'll do a few tin can penetration tests first before aiming at a grouse.
The one time I tried and it penetrates wet cardboard at about 20 ft with fresh table salt with no rocks. It had about a six inch flame out the end of the barrel.
I was told the only way to confirm the penetration damage is to use ballistic gelatin but that’s a little pricey to play with.
I’m still hopeful to find a tested non lethal load, for a "Critter Ridder" harassment load but I haven’t found anything documented to date.

Rock salt is very harmful and toxic if it enters through the skin.
The wound will never heal properly until the grain(s) is removed surgically
or disolved (it may take years).
Unlike the lead, which is very toxic as well, but
the body can build a coating around a lead pellet
and that prevents some of the lead toxicity since it is somewhat contained.
