    Wow, 6 years as a 45B and I have never seen a 203 come apart like that

    SO, I'll guess that someone loaded that round with something like Tannerite or similar composition. If that's what happened, shame on them.

    Even more likely is that they loaded it like a "normal" round. the 37 (and 40mm) rounds use a "high-low" pressure system. Below is a brief description of the system, along with some cutaways of various loadings (note the powder chamber size, VS the empty air space)

    (Specimen, description and and photos courtesy of Mel Carpenter) quote: The 37mm version is shown here, with the sectioned round done by Paul Smith. It used the same basic high-low pressure design of the 40mm M79/M203 series of grenade cartridges where the propellant is contained in a small chamber - a copper cup in the MBA version - so it can burn properly while being contained under high pressure. The high pressure ruptures the copper cup, allowing gas to flow into the larger cartridge base where it's pressure is reduced in order to propel the stun-bag at it's low velocity of about 150 feet per second.

    Didn't have to watch the clip to visualize what happened. As I've written a zillion times about "experimental" reloading:

    The interval between trigger and tragedy is far too short to have second thoughts.
    I may be a bit crazy - but I didn't drive myself.
