I've been meaning to try making these wax slugs myself, it's a hell of a lot cheaper than buying factory slugs. I have changed my mind.
Glad you're alright, good luck in your deployment, and thanks for sharing.


Wax slugs are not dangerous if you don't switch out the wads like an idiot.


As a kid with a copy of the anarchist's cookbook, I used to do some pretty stupid shit with shotguns and never, ever, never not once hurt a gun or myself.  

Do you know what a fiberglass fishing arrow does to a car door at 850 fps?  I do...
 


Do tell.

One blown up shotgun per thread only.

No posting dangerous stunts.

Thanks, Mike.

Bore obstruction.


Yup. I've never seen a blowout like that that didnt have an obstruction as the cause.

OP: Glad to hear you are okay. When I saw the first pic, I said, "Uh oh!

So let me gets this straight...

You took a cup that was larger and replaced the factory one, so in the end your wax slugs were heavier then the original shot in the birdshot? Was there a noticeable amount of recoil?

That will do it. I guess you are not a reloader because a reloader would know, the heavier the projectile the less powder it takes. So you significantly increased the weight of the projectile and kept the same amount of powder. Its also worth it to note that birdshot uses somewhat flimsy casings that are not meant for higher pressures.


In red...

While you're possibly correct a higher chance is having a space in the shell where the powder sits. He did exactly what Cowboy Action guys do when they routinely blow themselves up: Underloaded a charge leaving a gap. The powder is supposed to burn from rear to front pretty uniformly. If it's not compacted, you can get more than one place the powder is burning from, exponentially increasing chamber pressures. (You can easily double or triple them)

Ever wonder why they put oatmeal or whatever in their underloaded cartridges to keep the powder pressed against the primer? Now you know. Whenever I hear about a newbie to the sport talking about how they'll pull a bullet, dump some powder, and replace the bullet, I get out of Dodge when they're going to fire. They do this to make it easier to fire fast and on target.

OP: The reason you experienced what you did was because you replaced the wad and replaced it with another one without it compressing the powder so there were no empty areas.

No i didnt mess with the powder but i did take the wad out and replace it with a shorter one out of a different shell which sat in the shell further down.  So my theory is that the added weight from the shorter wad and adding more bb's and wax.  I dont remember actually seeing shot #49 on the paper and i dont remember how it sounded because i wear ear muffs and everyone else at the range was shooting.  So its very likely the previous shell was stuck in the chamber.  Also would me taking the wad out and the powder not being properly packed cause anything?

After looking at the remains im a believer in barrell shrouds, 4" of the barrell vaporized and luckily the shroud absorbed what would have shot up in my face.  I shot this from my hip.  Also looking at my northface fleece jacket the majority of damage i received was burn, my sleeve was melted.

Again this was 100% my fault.  I dont question the integrity of maverick/mossberg but my next shotgun will be an 870 and i will never fire anything other than a factory load.  Thank you everyone for your concerns.  I guess its a good thing parents pray for they're kids because everything in the chain of events worked out in favor and i still have 10 fingers, 2 eyes and both my arms!

About 3:00 on the barrel pic-looks like deep rust. Maybe the barrel was somehow cracked already  or a while before and just took this long to blow up?

Probably because he shot 49 over pressure rounds and 50 was the magic number for kaboom.

One of the coolest guns I ever played with was a ruger MKII converted to arrow gun. With the dog training blanks that thing would launch a custom bolt flat for 25-30 yards easy. You could even use the factory sights
