OK, shotgun guys, I saw this, quite eye catching, pic on an NRA article.

What's up with the chamber flash? I'm guessing that this is powder still burning, literally as the shell ejects. Is this common? I would have thought that it would be engineered so that the chamber would be closed through combustion. I haven't shot shutgun a ton so this seems a bit off the wall to me.

Massive firepower and ammo choices ranging from slugs to less-lethal have kept the 590A1 in the military’s arsenal through present-day.

3" napalm round.

Since that appears to be a low velocity less-lethal cartridge, I've carried both rubber buck and a finned rubber "baton" round in the past, I assume shoving the light weight projectiles down the bore doesn't allow for enough dwell to allow all of the powder to burn up. I would guess the shooter didn't wait very long to open the action as I've never noticed that much fire coming out of a shotgun ejection port from less lethals, even at night.

Possibly a bad primer and load another round while shell was being ejected and shell went off.

It's a pump gun, there's no dwell time or gas pressure involved....dude racked it as fast as possible, and thus....flames.

Yup, a 590 is a pump, I have one. Great piece of mechanical engineering. A bit dated but still great.

Yep. If you look at the muzzle, there's still smoke coming out of it, too.

These things have almost no recoil and you lose the sensation of shooting a shotgun at all, I feel like this leads to incomplete strokes of the pump action for some shooters. Must be a decision to over do the deliberate and quick stroke to reduce that chance.

I must be over sensitive. I can feel recoil from a pump shotgun without much effort.
And I'm not sure how not feeling recoil has anything to do with when you rack it, or how far you rack it.

And I'm really not sure what that last sentence means? Are you saying the guy deliberately chose to give the deliberate and quick stroke some extra ooomph?
I'm not sure that racking it harder causes flames out the ejection port....or are you not even talking about that anymore?

 

[RACHGIER]

Meh. It's just fast racking. As soon as you pull the trigger, you're racking the next round. You won't get a high ROF if you don't rack that bitch immediately.

And that looks like an 870. You can hold the trigger down and pump away. Just like a revolver.

Interesting. We had a pump .22 when I was a kid that could be fired that way. My Father was not amused when I did that. Howsomever, I thought the Gun Police made all makers change designs so that could no longer happen. Guess I thought wrong - I often do.

Me too. But I think you're right, but that there are plenty still out there that can. Maybe not that guy's in the photo, I guess.

Since it’s from an article about the Mossberg, I’d like to say you may be wrong.

But given the state of the modern media….I’m not saying that.

However…I think the trigger guard shows it to be a Mossy.

I will absolutely take your word on that, because I didn't read the article. 🤣

You should have played the bad cell network card. All would have been excused. 😆

Well in truth, that was a contributing factor, but mostly I just blurted. 😇

I'm not sure if you've fired these less-lethal rounds, or not, but given the other distractions during a course of fire it's pretty easy to miss the normal cues that the gun has gone off. My old unit had tacticool 870s and they weighed enough that there was no perceptible recoil when you fired the finned batons or rubber buck. If you have ear-pro in then you don't even really hear the pop of the primer going off over other people racking their slides. So the extremely light projectiles and greatly reduced powder charge makes these a different experience entirely. We were always taught to exaggerate the pumping action and put more force into it than we thought necessary just in case a shell got stuck in the chamber, or was slightly out of round and didn't want to feed properly, I think since these less-lethals don't really obturate, the racking action tends to be more violent than with buck because you apply the same amount of force to something that offers almost no resistance. That's just my experience though, I'm not sure why this guy pumped the action so early, because it's clear the powder wasn't done burning, but maybe he was trying to demonstrate rapid fire or something.
