I’m not sure if this is an Ultimate Ammunition product, a Cadex product, or a co-branded venture, but I am sure it’s pretty darn cool. For those who take their extreme long range (ELR) shooting extremely seriously, precise muzzle velocities matter a whole heck of a lot.

Gunpowder and primers are temperature-sensitive, with changes in temperature causing small changes in burn rate. A 40-degree cartridge won’t fire the bullet at the same speed as a 108-degree cartridge will.

Now, for most of us, the difference in muzzle velocity between 2,660 FPS and 2,667 FPS doesn’t matter. In fact, we’d consider that a very tight deviation. But if you’re doped in for a 4,000-yard shot, that 7 FPS can shift your point of impact by a few feet.

It’s over-the-top, but this temperature- and humidity-controlled ammunition case with an individual foam slot for each round was one of the cooler things I saw at SHOT Show.

    So how do long distance shooters compensate for a day warmer or colder than the time they dialed-in their rifle?

    The moment you chamber a round, it begins warming or cooling to the ambient temp of the barrel…

    • Thinking the same thing. This “ammo humidor” is a nifty gadget for those times when we like to take those 4000-yard shots (do those include a shot glass?), but any distance beyond half a mile is going to have several factors the shooter absolutely won’t know about or be able to control from his position. Wind, changes in temperature along the bullet’s path, thermals (a combination of the two), the infamous Coriolis Effect, etc.

  3. Off Topic but RIP Meat Loaf.
    I’ll never forget my time seeing the midnight showing of the Rocky Horror Picture Show. The theater audience participation was outstanding!!! The rice, the toilet paper, the lighters, and the crossdressers!
    It was all great innocent fun.
