dust even from something like grain can be explosive under the right conditions. any ever seen pictures of a grain silo explosion? it's not pretty.

so, give that grain in of itself would not be considered explosive, but gunpowder by it's nature and design is, wouldn't a prudent person at least think that given the right conditions, that static electricity could cause it be set afire?

why not err on the side of caution and play it safe in regards to static electricity and gun powder.

Well, I wonder why the reloading industry as a whole does not recommend grounding everything they make. if there was even the slightest chance of a liability they would have everything grounded from the get-go.

They could still be in the denial/"cigarettes don't cause cancer" phase before they are regulated to death by the federalis.

Well ....thousands of people view these threads...has anyone seen or heard of static electricity setting off primers or powder? In high school (Catholic) we had to wear coat jackets and Hush Puppies. (for all of you young'ins, those were a very soft shoe which did NOT leave any scuff marks.
Anyway, our seats and seat backs were plastic, and between the wool jackets in winter, the insulated shoes and the seats, we could stir up quite a spark on everything we touched....including the ears of some unsuspecting fellow in the seat ahead of us.

You really need to quit over-thinking things.
This isn't rocket science.
In the 30+ years that I've reloaded,I've only had one primer explode on me. I was priming my cases on one of my presses,and something set one off when I pressed it into the case.
It was pretty loud,and scared the crap out of me,but that was it!

I wouldn't worry too much about static electricity,but I also wouldn't reload in a room with carpet in it.

No never, can't happen. Did you watch the video I posted earlier? Simply can't happen.

never and can't are pretty strong words. the probability might be slight, but under the right conditions, i believe it's definately possible for static electricity to set off gunpowder.

and i'll state again, gunpowder is flammable and explosive by nature of it's design and purpose, grain dust isn't, but even grain dust can cause massive explosions under the right conditions. Google grain silo explosions.

One of our forumites worked for a ammo manufacturer and had a primer explosion that was due to static, IIRC.
My explosion wasn't caused by static. It was a jam in the hopper and they went off when I tried to clear the jam. Not saying it isn't possible though. When I worked there everything was grounded from equipment to employees and even conductive paint on the floor (or that's what the safety manager said). It's better safe than sorry. If I were you I would ground. Better to have it and not need it than to need it and not have it.

Apples to oranges at best. Dust comes in all kinda forms, from wood to grain to man made products and YES it can and will ignite and explode from static.

Powder is not "dust" and is not going to ignite from static on the bench in it's original form.
