What is a phosphate compound? When I go to the range, I am shooting either smokeless powder (nitrogen based) or blackpowder (sulfer/pottasium based). If someone is using a phosphate based propellant, I have to think a lot of people downwind are going to be getting sick from the exhaust in short order.

I did get my vehicle searched once after I had hauled a bunch of spent brass cases back from the range loose in my trunk. I removed them all, but the residual powder and ash that was left in the trunk was enough the dog reacted to it and I had to wait while they parted out the back end. I told them what happened, but they still had to search, and in the end we were both glad that the dog did his job. It was a good test, albeit a little inconvenient.
