sand versus shot in speaker stands

Interesting issues regarding shot and lead. We have loaded our own shotgun shells in all 4 gauges for 60 years. 12, 20, 28, and 410. We use MEC 650 loaders, and we are competive internationally ranked skeet and trap shooters. At any given time, we have 300-500 pounds of bagged lead shot on hand, and have yet to have a 3 headed baby, nor have we glowed in the dark.
Now if I can just get rid of this nasty eye twitch...

One thing I neglected to mention, we don't physically handle the lead shot. It is taken from the bag it comes in and deposited in an awaiting supply tray, then fed into the MEC presses.
The way it is stored in it's original 25 pound sack has never caused us problems.

That being said, I sure wouldn't ingest it, nor would I handle it for any length of time without hand protection, and I sure wouldn't let the kids play with it.

The cost of lead shot has sky rocketed over the last 50 years, but the alternative in steel shot is even more expensive in 25 pound bags.

I agree with Jaybo in much of what he says. I'm not a big fan of sand for moisture purposes, but if you need shot for this purpose alone of weighting down your stands, use steel shot.
