New Ammo to Torch: 20 Ga (best yet!)

[Badger Arms]

This is the best shot yet. If you haven't seen the other videos, stay tuned to the end of this one and there will be links:

What interests me and what one of the comments suggested, was what ignited the powder. It would seem obvious that the primer did, but could the torch have lit the powder through the flash hole? Any comments on why this shot turned out different than the previous 12 gauge shots?

Safety precautions were taken: Filmed at a closed range stall with 360° barriers. We were behind barriers for all centerfire shots. Eye & Ear protection was worn. Extensive research was conducted to include SAAMI video, Julian Hatcher, and Vincent J. M. DiMaio. Do not try this at home! Serious eye and/or skin injury can result.

Interresting. I imagine that the powder was ignited by the primer, but that the powder was still burning when the shot was ejected from the end of the shell, some of that powder may have been ignited from the torch.

Generally speaking, smokeless powder burns a good length down the barrel behind the bullet or shot charge. When it is not confined, much of it may remain unburned as you mentioned in some of your other test, such as the 5.56 test.

As to why the results differed from your other shot shell test, the higher brass kept the heat off the plastic body of the shell, plus it may have given a little more strength where the powder charge was, but I believe that the main difference was the effect of the heat on the plastic case.

If you can find some paper cased shot shells and repeat the test, that might be the best way to determine why the difference.

Really cool demonstration there. But read on about what happened when I attempted something rather similar.

So, back in my early beginnings as a new reloader, and not knowing any better, I did something stupid and potentially deadly. I tossed a 209 shotgun primer into the BBQ. I was thinking it would just pop like a fire cracker, not at all the result. Within several seconds of tossing it in, it exploded with a very loud bang, enough so that it rang my ears. It blew a hole through the side of the BBQ, similar to that what one would expect if shooting the BBQ with a 22 LR. While searching for the primer, I discovered a deep dent that had started to penetrate into the metal siding of the house. I did find the primer laying on the ground, but it had separated from the cup it is pressed into when manufactured. The cup apparently provided the characteristics similar to that of a chamber, thus turning the primer into a projectile as it shot out of the cup. A standard CF cartridge primer, like such that is used to prime metallic cartridges, is supported by the primer pocket in the cartridge.

So due to my experience, I was expecting exactly what your video demonstrated, which was for the primer to separate from the cup, thus becoming a projectile in it's self, producing some pretty impressive velocity also. Notice that the primer cup remained inside the primer pocket of the shot shell?

I'm guessing difference is high vs low brass. Of course, you are missing the high brass 12 gauge for comparison. If gonna go back I'd add a slug, and high brass bird and an all brass one. Always fun to watch things go pop.

More irresponsible fun with a blow torch and ammo!

You've got it right. My analogy was that the primer pocket acted essentially as a mortar and blew the back of the primer out leaving the anvil.
