Canmunition Update #2 – Test Firing

Part One – Canmunition: The Ammo Cache Answer?

Part Two – Canmunition Update: Opening the Cans


I finally got to test out the 9mm ammunition from each of the four Canmunition test cans. I was shooting the ammunition out of my Springfield Armory XD9. The cardboard targets were 15 yards out. It was a very brisk 35 degrees out when I was shooting, and since it was the first day of hunting season, the range was incredibly deserted

Let me get two things out:

1) Yes, I am not the greatest pistol shot in the world. With that said,

2) This was simply a test to see if it went bang. I wasn’t being super hard on myself for accuracy.

I started with the Buried can and the Water can and then moved to the Freezer can. Finally, I shot the Temperature can (I was admittedly a bit nervous with that can since I knew the highest temperature I observed was 144.6 degrees F and I did not know how that would affect the ammunition.

The big takeaway is that all 360 rounds went BANG! I had no failure to fires at all. I was quite surprised that neither the freezer nor the temperature ammunition was affected. I was expecting the freezer ammunition in particularly to have one failure because the condensation on the bullets after the thaw would have affected the primers, but that was not the case.

I did, however, have two failure to ejects with the ammunition that was stored in hot temperatures. I don’t particularly know if that was a coincidence or if the temperature somehow screwed with the case. Everything else, however, worked perfectly fine!

Patriotman’s Opinion

I think that the Canmunition test was a success and I am quite pleased with the results. I do think that the Water can would have corroded if it was submerged for an extended period, but it can certainly take 6 months worth of it. I also would hesitate to store the ammunition in an area not temperature controlled for heat because I don’t know how long term exposure to heat affects the ammo AND I did not like that the vacuum seal on the Temperature can was broken.

I do not hesitate, however, to recommend the product. I think that Global Ordnance hit it out of the park with this product.

Aftermath

EDIT: A comment from Historian below:

PatriotMan:

Failure to extract on the high temperature rounds *may* be indicative of high pressure from the fired round. This is often associated with higher than normal variation in muzzle velocity. I vaguely recall reading something years ago about ammunition life being a geometric function of ambient temperature, one reason I try to store ammo in cool dry temps. The case and the projectile are not likely to see any significant change in properties at those temps, but the powder and primer both degrade over time. At average storage temps of 60 degrees with humidity under 40%, ammunition will last for decades.

It is worth noting that temperature extremes are buffered by the earth; caves are great for storage, and properly buried underground caches work well too. Water is the real enemy here and proper waterproofing is key. If you are going to store ammo above-ground in a non temperature controlled area, keep it as close to the ground as possible, and on the north side of the building if possible. This makes a big difference in the average peak temp the ammo will see.

    Thanks for this test. I have a few cans of both calibers and have been reluctant to put them to the test due to the cost. They are also in a temp controlled environment until we get closer to TEOTWAWKI.

      You are most certainly welcome! Thanks for stopping by!

    Man I can’t tell you how much we appreciate the testing

      Glad that you find it useful brother!
