The Small Arms Thread, Part 8: 2018; ICSR to be replaced by US Army with interim 15mm Revolver Cannon.

This could also be why I have had no trouble with mine.

I buy ammunition in bulk, especially practice ammo, and rotate the newest to the back so I'm always shooting the oldest first. This still leaves me shooting 500-2000 of a given ammunition before I'm changing to a new brand or even really divergent lot numbers. It's also usually my reminder to do a thorough cleaning of a gun.

I also live in the pacific northwest where temperature etc aren't super divergent.

I'm curious to see whether my impending move to Kansas will change the behavior of my guns.

[Meplat]

I was alternating mags of steel and brass.

9x19mm ammo is all over the place in terms of dimensions, bullets and propellant. No big surprise, it's been around forever and everyone has a slightly different take. Like chili.

So you're right, I should have said unreliable with that particular ammo. It might hum along with something else.

I wonder if .40 is more consistent, having had less time to diverge.

 

9X19 is one of those cartridges that can be all over the place, reliability wise.  Case metallurgy just made it weirder.

 

One of the better I ran into was an Owen SMG that'd run away with any 115 grain commercial fodder.  Basically the "modern" loads would kick the works just back far enough to cycle the piece but not far enough for the sear to catch.

My Glock G22 Gen 4 has over 30,000 rounds through it at this point and I could probably count the amount of malfunctions I've had on one hand. even when swapping out to a G31 barrel.

 

Though, I'm not sure if that's because .40 S&W/.357 SIG are more consistent or because it just happens to be a very well maintained Glock.

[Sturgeon]

I would be shocked if .40 S&W were as inconsistent as 9mm.

 

Also, lol you like .40 S&W. Pleb.

I'm already getting some rifles and likely a couple new pistols, I sold for POF-415/308 Upper for more then I thought I would, so, now in the market for a DI AR-15, among many other things on my list.

Cartridge OAL issues and available barrels nixed that one early.

[Oedipus Wreckx-n-Effect]

I had a 38 S&W webley for a hot minute. Didn't have any ammunition for it, but I put the pistol together from a bag of parts. 

 

They were meant to fire 200 grain bullets. The speed on them couldn't have been more than 500 FPS or so. 

[Khand-e]

So, the designers of the 2 sizes of "screwdriver bullit" have apparently come out with a flathead and sqaure design to help complete your bit set!

 

 

 

[Collimatrix]

That's revolutionary!  That's groundbreaking!

 

Fortunately, for Winchester, an SXT could be made into a socket head hex drive with only minor modification.

[LostCosmonaut]

That's revolutionary!  That's groundbreaking!

So what, my 5.56 rounds are groundbreaking too if I shoot the dirt.

[Collimatrix]

The first generation of .40 S&W pistols were basically 9mm designs that were bored out to accept the new, fatter cartridge, and this was a bad thing.  There were some that were purpose-designed for the .40, but they were not the majority.

 

I actually suspect that many .40 S&W guns today are designed for .40 S&W, but you wouldn't know it by comparing them to their 9mm counterparts.  They aren't any beefier.

 

What I think is going on is that gun designers have gotten (a little) wise and they're designing the .40 first.  So the 9mm pistols end up being a bit overbuilt and a bit bigger than they would otherwise need to be, but the .40s are adequately strong and there's some savings manufacture of shared parts.

 

You can see some evidence of this if you compare a .40 S&W XD and a 9mm XD.  Compare the magazines and the frames.  The magazines are actually the same width, and so are the magazine wells of the frames (the frames may in fact be interchangeable, or at least start as the same part in the factory).  The only difference is that the 9mm magazines have some extra ribs stamped into them to take up a bit of the width inside the magazine and thus feed the narrower cartridge.  Clearly, the magazine and frame were designed around the .40, and the 9mm was a conversion of this design.  It seems logical that the rest of the pistol is the same way.

[Sturgeon]

Yes, and that's related to a key argument that 9mm pistols are way, way, way stronger than the ammo we fire through them. I am convinced that - minor parts failures and mass balances aside - you could take any modern NATO-rated pistol and run 50,000 PSI ammo through it all the time and from an explodey perspective it would be just fine.

[roguetechie]

I still want a reputable western manufacturer to clone the gsh-18 without the shitty build quality and bad materials.

Despite the extremely poor initial production models I think that the basic design could be genuinely ground breaking from a cost, production, and usability standpoint.

It's a phenomenally cool design that was let down by bad manufacturing.

Don't know if this would be of interest, but too bad

 

 

It said this change in strategy would rule out deals with countries such as Saudi Arabia, Mexico, Brazil, India or even NATO member Turkey.

[Oedipus Wreckx-n-Effect]

So this is pretty neat.

Yeah, that's what happened.
