Only if you are not shooting 10mm!
Tracers and some specialty rounds could, but I can tell you this, I don’t let people shoot tracers in drought conditions.
This whole thing is a joke.
The notion of a spark from a ricochet is ridiculous.
Folks are simply trying to demonize shooters and blame them for fires.
I have a 10mm conversion barrel for my G30 and they don’t hurt as much as when I shoot 45acp through it. I would rather shoot 10mm all the time if it wasn’t so bloody damm expensive.
As far as that diagram the flash may be more than the others but how could it start a brush fire without the shooter noticing?
