The gas bled off doesn't reduce it to a noticable degree. Check muzzle velocities for the same loading out of pump guns vs gas action autoloaders. It's not really significant.

The recoil spring aspect makes no difference whatsoever.

I tend to think if aimed correctly buckshot does fine. I dont agree with the new yorker.

This dude said that buckshot didn't reliably drop opponents.  Meaning that they would still be conscious and able to fight back even if he shot them first.

There is usually one or two very small holes in the barrel where the ring attaches to the magazine tube. After the wad passes the hole, a very small amount of gas is bled off that operates the piston/rod to cycle the action.

Or, in short from Chuck Hawks, a gas operated autoloader bleeds off a small portion of the expanding gas created by the burning gunpowder when the rifle is fired. This gas flows into a cylinder, where it forces a piston to move the operating rod that works the action.


Again, velocity difference is negligible.

What Toad said is spot on.  The gas used to cycle does very very very little to the power of whatever you're shooting be it a slug or bird/buck shot.

I'd like to find a nice Belgian Browning Auto-5.  My uncle has one but unfortunately for me he's in good health and won't part with it until he dies ;)   I'd use it over my 11-87 autoloader any day of the week and twice on sunday.  It shoots very well and the time to fire an accurate second shot is shorter than using a recoil shotgun like the Remington with the gas system to help cycle the action.  I've been lucky enough to take 2 deer with it and will be standing by with a shovel just in case he decides to be buried with it.

Yeah the load should be mostly accelerated by the time the wad passes the gas port anyway.

Could be this cop doesn't have very good aim.  A winging shot could definitely leave someone combat effective.  

Could he be talking about birdshot?  I could see that.

Place your rounds center mass and you won't have those problems, even with smaller rounds.  Even a well placed .22 will kill or disable, but with something that small it is of course all about placement.  

A weapons test, purely for the hell of it, yesterday showed that 9mm Luger FMJ does NOT penetrate a keg shell from about 10-15 yards unless it strikes a seem or a previous impact.  I've got some totally flat and polished cores to prove it.  Bird, buck and slugs all have no problem whatsoever.  2 SKS's, needless to say, turned it into a colander.  The birdshot had about a 1.5-2 inch spread and forced its way through the front, but not the back, because of its focused energy.

I can say that I've seen buckshot blow clean holes through a solid belt buckle before too.  I could see maybe 3 count having a couple pellets miss for some reason (bad aim) and only one not hitting critically.  

My friend is looking to buy an auto-shottie.  We don't really have any experience with them.  What would you guys recommend?

Also, we noticed that we only find them in 4+1.  Is this a legal thing?  Do the mag tubes incorporate the gas piston or could they potentially be swapped with a standard pump tube?

A friend of mine has a Benelli auto like this one. I thought his held 7 rounds but I will have to check. Maybe he has a mag extension. I know it will empt the mag before the first empty hits the ground. Im pretty sure its not a cheap shotgun though.:)

The weapon choice is not that big of deal in the long run in a close encounter. The person holding the gun, their training and nerve under fire will make it or break it.

The NY cop also didn`t state how many brewskies he had a week to go along with his bar tales.
