    Most commercially available anti-static preparations are of the fatty acid amine family. They work by taking moisture out of the air and holding it in the molecular structure of the amine. Over time amines dissipate into the air. They generally have a fishy odor so you can count on have a dose of perfume present. Also, if you take a fresh Bounce sheet and rub your fingers on it then rub your fingers together you will feel a slight slipperiness. That's the amine. Touch you tongue to a Bounce sheet and you'll get a soapy taste.

    They are very effective at what they do for the cost. That is the good news. Bad news is they tend to be corrosive when used excessively. Don't worry about corrosion in your firearms. The concentration is just not sufficiently high. The electronics industry chased its tail for years because it insisted on using anti-static materials to reduce losses due to static discharge yet absorbed increased losses due to corrosion. Opposite ends of a teeter-totter.

    If you live in an area that gets dry during the winter because of forced heat, try running a humidifier (cold mist, not a hot mist). It puts moisture in the air and knocks down any electrostatic charge buildup.

    Speaking of charge buildup, pay attention to the seat you sit on and the clothes you wear. Artificial materials like genuine Nogahyde and vinyl will build a charge when you scoot you butt across the chair. Combine that with manmade fabrics and it is possible to build significant charges. Cotton absorbs moisture from the air and tends to dissipate charges.

    There! Now where is that life I hear everyone talking about ?????

    Waitone .. thx dude ... that seems very logical. More or less backs up my thinking or remembering that static is surface oriented.

    Unfortunately these days ... man-made fiber is everywhere ...... even on a winter's day when very dry .. I can draw a massive spark when I get out of the truck and touch the door!

    I do tho almost from habit ''ground'' myself often with large metal objects ... to reduce build up. If messin with puter boards then I wear an earth strap.

    Hum...

    There's a song in that... (with SEVERE apologies to the ghost of John Phillips...)


    "All my socks are sticking, and my hair's on end
    I've just had a shock from my chambray
    I'd be safe and clingfree, if I was discharged.
    Static discharge dreamin' on such a winter's day"

    "Stopped in to a store I passed along the way
    Well I got some Bounce sheets and I went to pay
    You know the manager liked the cold
    He knows I'm gonna pay
    Static discharge dreamin' on such a winter's day."


    Christ, I need to keep my day job...

    Anti-Static Mat.....

    I'm reviving this thread, as I see static as a real viable source of ignition while reloading.

    Every winter, I would run two humidifiers all winter (those large console-type) to keep the air moist - at the expense of moisture on windows. Last winter was the first winter I have not used them.

    My reloading stuff is all in my basement. All summer, I control humidity by running a dehumidifier nearly full-time, over a drain in my basement floor.

    I am looking to purchase an anti static mat to use at my reoading bench, complete with strap for around my wrist.

    All it takes is one tiny spark, at the wrong time, and pffffft - everything in flames. I could run to the top of the basement steps and grab a 5# CO2 Fire Extinguisher I have there, but by then the fire could be pretty large!

    You could move to South Georgia ... 98++ degrees, 98%++ humidity... In the shade!!

    No static.... but you have to watch out for RUST!

    I grounded my press through a 1meg resistor and 'never' have a static problem.

    Cost, about 50cents.

    Digikey can sell you one, start here. They'll also have wrist straps, separate, and if you pick the right mat, it'll have a little spot you can plug the strap into.

    Any of their competitors, like Mouser or whatever, will have them as well.

    Searching around for 'static control' or 'esd safety' on any of these sites will probably turn up all sorts of fascinating products.
