Just great... talk about bad timing...

Can lead or copper-jacket bullets with no steel, tracer, or incendiary material in them start a grass fire?

I wouldn't think so, but there's a lot of ammo out there that has steel in it. Bimetal jacket and such. Ricochet off a rock, throw a spark in dry grass and you've got yourself a fire.

It may have not even been due to shooting.

About 10-11 years ago in Wenatchee a girl my friend was dating started a fire by driving her little car into some dry grass. The heat from the engine started the fire.

It was probably the catalytic converter. Farmers had a big problem with this back in the 80's when they first started putting them on trucks. They would have them cut off to keep from catching there fields on fire. I have measured the temp of a few at 800 degrees when they are clogged.

I've never heard of it. Had to be tracers or tannerite or something stupid for the dry conditions. Knowing your backstop is part of responsible shooting too. These guys had to be doing more than just plinking in a safe pit to have started a fire.

Real tannerite doesn't cause fires.

I still want to do some testing with it, I do not know if it really contains enough zirconium hydroxide to completely convert everything to water.

It is still an ammonium nitrate/ aluminum explosion.
