Local fire crews were able to put out the blaze. The recreational shooters responsible for the fire were cited and fined $525. Tracer rounds and other incendiary ammunition are illegal under the Federal Code of Regulations. This violation carries a $525 to $5,000 fine.

Tracers are built with a small pyrotechnic charge in their base and are able to start fires. So far this year, nearly a dozen fires have been caused by "irresponsible" shooters.

Todd Harding did a story 2 weeks ago about bullet caused fires on the Pawnee National Grassland.
