Although easy to like and will burn the hair off your knuckles (LOL!), smokeless powder is a flash in a pan!

Looking for something that really works and I mean really works even after being stored wet for a long long time! Well by’golly get’ya a small jar of good old fashion Vaseline from and a magnesium fire starter stick from your local Wal-Mart. So simple of an operation I bet David can do it. Take a 2x2 inch piece of cloth and saturate it with Vaseline and scrape a little magnesium on it and hit it with the flint side and now you have instant fire 6 to 10 minutes of flame, now compare that with any other lighter and remember you haven’t really used your fire starting resources at all. I still got the same Vaseline jar in my back pack some 10 years ago and still work as good as the day I put it in.

As long as you pour it out to light it it shouldn't blow up. I've lit smokeless powder and it does burn pretty fast but it is also a hot fire.

i've never tried it but i think i might

Unless you are with one of those "historically accurate" re-enactment groups, in this modern era just use the simplest solution:

I didn't go through the full survival course, just the "3-day special". It was at the base in Rome, NY. It was darned cold.

The instructor did show us the flint-and-steel thing, and even a demo of the primitive toots, but mostly he told us about the miraculous, simple, cheap Bic lighter. Even ripped in half with no fuel, it makes a great spark.

I had to think about it. You can custom order fancy kits and tools and waterproof this-and-thats, but you can get a 6-pack of Bic lighters anywhere. And I did.

I'm weird about it in the mountains. I have them all over me and my gear. Shirt pocket, pants pocket, pack, belt case. We got stuck behind a rocky hill in north Georgia one year, and took a wrong turn that cost us hours out in the cold. We weren't lost, but when we got cold enough, it was moments to a good fire.

Now, some of the others' advice is also good. However, having to make sure the powder is dry, AND the matches, AND the lint, as well as possibly only having one shot at getting a fire (as some of the tiny kits only come with bits of these items), it seems better to have an instant fire generator with you.

i also use paint thinner gives you a nice hot burn and great to start a fire

I suppose it would be worth a try if you were stuck without anything else to use, and wanted to empty a cartridge, but if you are thinking ahead to take something there are better fire starting materials to pack. I would suggest either a commercial tungsten firestarting stick, a 35mm film canister with dryer lint, or extra fine steelwool to start and also, like buckmaster said a piece of logstarter. Another thing that I always carry with me is a couple of the 'joke' kid's birthday cake candles that start back up when blown out.

Smokeless gunpowder is hard to ignite, and it burns very hot and very quickly once you get it going. You would be better off with a magnesium fire starter, and a sandwich bag full of cotton balls soaked in vaseline. A plumbers candle, or some tea-light candles would be a good addition too.
Building a fire is not that cosmic, you don't need jet fuel or explosives or gunpowder to get a fire going. Just gather lots of very small dry tinder (dry grass, very small sticks) and an armload of pencil-sized sticks and then your larger wood. Get everything ready, then light your tinder (magnesium+cotton ball) get your dry grass or other tinder burning and then get the pencil sticks burning then regular wood. Practice in your back yard if that sort of thing is still allowed where you live.

I would get a fire striker that you strike with you knife you can get them at walmart

The only way I would use smokeless powder to start a fire is in a truely survival situation and I had to start pulling bullets. there are about a dozen better things out there, gun powder burns too fast. try the magnezium blocks, soaked cotten balls, saw dust in a a pill container or a Zippo :)

I think you would be better off learning where you can make or get good tinder in your local woods. The problem with the powder is that if it get's damp whatsoever your screwed. Know where to get good tinder from nature and you will never have to worry about gwtting your fire started.

I've used Q-Tips soaked in citronella oil used in lamps. They light easy and burn like little torches. I keep them in a sealed old pill bottle.

I would say no...You want a long-lasting flame, So, Unless you have a LOT of the stuff, Then I would say no.
