Squib round shoots through magazine of competitive shooter's rifle - GIF and video

[Jon]

Shooting competitor gets a squib round (projectile fails to exit the barrel), fails to do a proper check (perhaps because he was competing), and the next shot assumedly causes the squibbed bullet (and/or the subsequent one) to exit through the magazine. Best case scenario, although the lower and other parts are probably trashed.



Good explanation of squibs, with the telltale click and puff caught in action at 1:38:

2:06 video:

Note how frustrated the shooter is. This is when we make stupid mistakes. Also note that this guy, like the top shooter, would likely have fired another round. The difference is that this shooter has observant instructors/mentors nearby, and they carefully talk him down ("there was...there was a click there...there was a puff").

Having seen the results of too light a load in a S&W .38 revolver, when such things were legal for 'target' shooting in the UK, it's not unusual for the shooter to miss the signs. With the revolver the second round didn't go until he pulled the trigger on the third, going down the outside of the barrel, the acting RCO stopped him at that point and they tried to extract the cases, the unfired rounds came out ok, the fired cases had shock deformed the cylinder chambers when the light charges detonated and wouldn't extract, the third rounds bullet was found stuck behind the firsts 2/3rds the way down the barrel by the gunsmith who declared it was scrap!

I'm not familiar with that particular model rifle but it appears as if the firing pin had stuck. the bolt moves forward when he pulled the trigger but nothing else happened until after he laid it down possibly some dirt was dislodged allowing the spring to push the firing pin allowing the rifle to discharge. I might suspect a bent firing pin as well.

For me, it's a "cow boy reloader" accident, in the bad sense of cow-boy, shooting at a time more than 15'000 rounds a year, I've never seen such a problem, but in "Sunday2 shooting at 25 meters i see a 357 exploding near me with a load without powder and after a normal one, the guy buy all reloading material and thinks it was easy as buying a beer, I think it sells all his material after that, it was a Taurus 357, very solid gun at all…
With military ammo, I had with very old 7,5X55 one round which not fire but never seen a multiple load with other ammunitions.

[Frank S]

A lot of guys who own .357's will buy .38 special ammo to fire through them because it is cheaper has 1/3 the recoil Their problem arises when they go too light like ammo that would be better suited for a short barrel snub nose than a 6 or 7" barrel both likely have the same 1-16 twist rate but the longer barrels can require more pressure than the light load low grain weight bullets could develop Not so much problem with store bought ammo but many hand loaders don't get their powder grain correct all of the time. Guys who load dumb-dumb rounds or rounds that have deeply hollowed out bases often load too hot for the weight remaining in the bullet causing them to over expand and squib.

This is why you shoot slowly and pay attention. When reloading you check, recheck and then recheck the recheck.

[Okapi]

Yes, at each operation when reloading is a check list to be totally observed, no problem in more than 20 years of reloading and muzzleloading…

When my father, long since passed from this mortal coil, was teaching me how to hand-load he always stressed "never rush, always layout and work logically" and if disturbed pour all the power back from any unfinished rounds back into the bulk measure and start again. Check weigh regularly and if your not sure pull the lot and start over.
He was asked by the local Police in the late 1960's, along with several other hand-loaders, to analyse some reloads following a fatal 'accident' involving a toggle cross pin failure on a po8 Luger, the toggle hit the shooter in the forehead killing him, every round was double charged behind a heavier than normal cast bullet. He said it looked like the guy had literally just poured the powder in to leave just enough room to seat the bullet.
