Gun Porn!

I'm still not quite getting it. I need like a diagram or something.

Or a gif.

The 320 was not made for smart rounds. It was made before the first Smart 40mm was made. It is based off of an already existing off the shelf launcher mad by HK for the original G-36 rifles which makes it's design pre-9/11. The side break allows it to use the longer less then lethal rounds and some of the newer longer dumb grenades because of its side break action. It also makes using parachute flare rounds a bit easier and opens up development for more grenade rounds because of more length available to it.

Caseless also is not automatically cased telescopic that is the solution it arrived at but not all examples are cased telescopic and instead have the propellant still at the base of the bullet.

Garcon:CTA or Cased Telescopic Ammo takes a lightweight polymer casing and wraps it around a block of solid propellant. Inside this block of propellant is a cavity in which the bullet sits. The gun is fired the casing seals the gaps and away the bullet goes.While this article is about CTA auto-cannon rounds it is the same design as the small arms in general. It has pictures to help you understand the structure of the round with some good cross section pics.

So the bullet is actually buried in the case and surrounded by the gunpowder instead of just having it clamped in by the rim and the gunpowder behind it?

Does that not mess with the ballistics or anything?

Tuffle, the M320 was chosen because it could support "smart rounds" in the future, the M203 was played out in that regard. Caseless comes in CT flavors and other types.

And no, CT ammo does not mess with the ballistics.

Taira: No it wasn't. There were no smart rounds to support none were even on the drawing board at the time. It was chosen because the new family of dumb rounds were longer then the older 40mm Grenade rounds making them too long to fit into the slide action of the old 203.

Specifically it was chosen so they could field the new low pressure extended range 40mm rounds which are 40x51mm where as the old 40mm were 40x46mm. The 203 opened just enough to allow you to load the old rounds with minimal wiggle room especially on those parachute flare rounds.

Garcon: Nope. There are a few different ways to ensure the projectile is propelled forward trapping the gas behind it. IIRC the LSAT uses an initial charge that pushes the bullet ahead just fast enough through the sealed bullet face which creates a sort of seal until the bullet is passed it that the follow part of the charge is burning behind the bullet. Keep in mind no one has exactly picked up expended casings from the LSAT and showed us what they look like so I am not entirely sure on that one.

That sounds awfully complicated compared to normal bullets. How much do these things cost?

No idea on cost but it is a brand new system so initial cost until full production is always higher. To top it off it would be the first weapon of its kind US inventory which might affect costs until production of ammo and weapons can catch up.

It really isn't all that complicated at all. Especially when you consider all the more complicated things that have been done with cartridges before.

Considering how expensive brass is becoming due to copper it can get really cheap if it is adopted.

some◊ pictures about CT ammunition◊

Apparently it is more reliable than the M249 but like that is something hard to beat.

The video has some animations showing the weapon cycling, now what I want to see is a rifle using CT ammo. I'd imagine with the diminutive size of the case, it would be possible to have a FN P90 style magazine.

The HK G11 had a magazine with ammo stored vertically. Apparently the 4.7mm ammo was used for research during the early stages of the LSAT program.

And Now To Make This Thread Title Ambiguous!

I don't want to know.

Still better than nutnfancy.

Any weapon videos shorter than 15 minutes is better than Nutfancy by default.

Based Hickok45.

I don't mind the Forgotten Weapons long length videos. Mostly because that time is spent with armorers level of detail on the parts.

Yeah, those videos are good. They really give you an insight into why some weapons are justifiably forgotten, like that one on the CMG 3 - if your receiver cracks after a lot of rounds are fired, then you as a gun are not up to standard. Especially if you are a machine gun firing 7.62mm NATO.

I must admit I lol'd at the piss-take on FPS Russia - that was funny, and not too far from how the show actually goes down whenever he fucks around with Tannerite.

FW is easily the best firearms-related YT channel.

^ Reisings SUCK!

Well, as the video shows, it was a perfectly capable sub-machine gun for the police users for which it was designed. The trouble was that it was rushed into production and military issue without any kind of rigorous testing program. Which probably gives the lie to the chuckleheads who say 'OMG why doesn't teh US adopt [insert the CoD fandom's belle du jour]' whenever some flaw is found in a US piece of equipment.

POTD: Pechenegs Galore.

Can I haz one? Please? Just donate one my direction Russians! I promise I won't use it against you in Syria!

Oh damn those are sexy.

LM Gs are usually exclusive to militaries, same with Grenade and Rocket Launchers. Sorry.

I have a question.

Why would anyone pay nearly 8000 dollars for a 1911?

Historical/collectible value or association with someone famous, I suppose? There really isn't much of a reason to pay that much for a new build M1911.
