FWIW (presumably not much), I was the first, I believe, to mention firearms in this thread. I did not do so as a political statement. I mentioned them because they utilize combustion to operate and that combustion, while typically confined to the gun, is not infallibly contained. In a stage 2 fire ban, I couldn't understand why a device that generates fire in such a fashion wouldn't be banned from use. I didn't understand why the use of a gun wasn't being banned or even controlled as chainsaws are. Each piece of equipment has a high enough likelihood to start a fire in a Stage 2 fire ban situation to be treated with some restrictions or prohibitions. That chainsaws were restricted and firearms not puzzled me. I may have sparked a political debate but I was not being political in my statement.
Understood. Modern ammunition burning very cleanly is really the answer to your specific question. It is a shame that the issue became politicized in a way that kept that from being heard. A different way of looking at it is the fact that, in terms of fire hazard, hunting jackrabbits with an airgun or with a "regular" rifle can be viewed as interchangeable in terms of fire risk. (Not in terms of other risks, and in each case safe shooting is a priority.)
