It's a 750gr bullet leaving the muzzle at four thousand feet per second. I really doubt a silencer would be remotely effective.

So... essentially a rimmed version of the previous GwPat?

Noted. I neglected to use the proper term.

[Absurrania]

I'm having doubts with its 12.5" barrel.

That would be a long-ass grip. You could just make it a double-stack.

In good conditions it actually does go up to 550 yards, but to be realistic, after 300 yards placing a shot becomes difficult. However, the Absurranian military puts an emphasis on mobility. It focuses on blitzkrieg tactics, and trains its infantry to accommodate such, so most firefights will not be at far range. That's where the LMG's & Sniper rifles specialize. And double stacking the M45 would result in a shorter grip, but double stack magazines have reliability issues. It is simpler to get used to the longer grips because then the longer magazines won't be exposed, unlike when you simply add an ext. mag.. And besides, an extra 5 rounds won't make the grip too long.

LMG Infantryman

Purpose: Pretty obvious. Carries the standard issue machine gun and provide suppressive fire for other troops to move forward to prevent enemy from advancing

Primary Weapon: M27 IAR. Fires the 5.56x45mm, the same the AK-102, allowing for better logistics. It entered service in 2010, when it began productions. Tests on it had already been completed by the military, courtesy of Heckler and Koch. It has a 30 round mag, but this small size is made up for with it's smaller size, weight, and somewhat better recoil management. It almost always has a bipod attached, and holographic optics are also popular. Despite being a suppressive weapon, it's overall performance still allows for more mobility than it's predecessor the M60.

Secondary: Either an anti-air Stinger missile or an M45 pistol.

Armor: Standard MTV armor that coveres chest, stomach, back, sides, crotch, and rear.

Sniper Infantry Man
Pupose: Pick off enemies from a distance and to scout out areas

Weapon: SR25. It fires the larger, more powerful 7.65x51mm round and has a much longer range that any other infantry weapon, aside from the Stinger. It comes equipped with a leupold riflescope, Mark 4, or an infared scope during guerilla or desert warfare. Introduced in 2001 to replace the larger .50 cal Barret, which had only served for a few year before being deemed to large and unweilding for most mass practical uses.

Secondary: M45. This consistency with the secondary pistols of infantry pistols allow soldiers to share ammunition much easier.

Armor: Same as always. Standard MTV.
Sniper

Also, from what I understand rimfire can't handle as high pressures as centerfire.

Too high ROF, far too heavy, ammunition is expended tooo fast, no practical aiming, too much reacoil, no practical purpose.

[Lemanrussland]

Why aren't revolver cannons used on ground applications?

They have been. Mostly as an improvised measure, though. The M163 VADS (M113 with a M61 rotary cannon on it) was used primarily for ground support, since it was never really needed for air defense. The Russians used SPAAGs (ZSU-23-4, 9K22 Tunguska) to escort their tanks and IFVs as a response to massed RPG attacks from Chechnya fighters. Not exactly rotary cannons in the latter case, but still in the same category.

The closest we've gotten to a full embrace of this kind of vehicle (an armored support vehicle, in this case to support tanks, carrying an automatic cannon) has been the BMPT in the Russian Federation, though that has not been really embraced as a standard weapon quite yet, and is still undergoing trials.

I assume rotary cannons (rather than just a plain automatic cannon) with obscene rates of fire aren't used because it's a waste of ammunition.

If you look on the Wikipedia article for "Revolver cannon" there are a few examples of 19th century revolver cannons. One more modern example I know of is the TNSh, a variant of the ShVAK, which was mounted on some Soviet light tanks (T-38, T-60). I'm not sure why it's not used more often in ground applications, for a firearm it would be way too complicated and heavy, and not really bring anything new to the table over a conventional recoil/gas operated self-loading rifle or machinegun.

[Spreewerke]

And double stacking the M45 would result in a shorter grip, but double stack magazines have reliability issues. It is simpler to get used to the longer grips because then the longer magazines won't be exposed, unlike when you simply add an ext. mag.. And besides, an extra 5 rounds won't make the grip too long.

An extra five rounds would make the grip 2.5" longer than standard, not including extra spring space for the magazine, and government models already have a fairly good-sized grip.


For reference, that would mean your pistol's height would be 7.75" tall assuming spring length in the magazine is the same, which I highly doubt it will be. Assume your pistol will be eight inches tall from the base of the grip to the top of the low-profile GI sights. If you're using aftermarket tri-dot sights and/or a magazine that extends below the frame, you'll need to add even more.

Your grip will be longer than your barrel.

[The Archangel Conglomerate]

Primary Weapon: M27 IAR.

Why? That would be kinda pointless when you could get the same if not better performance from, say for example, an AK-101 with 60 round casket. It simplifies training, logistics and makes everything look much more uniform and professional.

Secondary: Either an anti-air Stinger missile

Way too heavy for MG man to be carrying.

How does linkless feed and dual feed work?

Some questions regarding dual feed:

1. Does it fire one cartridge from one belt and the next cartridge from the other belt? Or what?
2. Would a dual feed gun work with a single belt?
3. Is there any RL system that allows you to choose which belt you fire from?
4. Can single-feed guns be ambidextrous-fed (able to feed from the left or the right side of the weapon), without changing the receiver ( for dual-gun mounts and the like ) ?
5. Would a dual-feed receiver be significantly heavier than a single-feed receiver?
6. Does dual-feed work with a revolver or rotary cannon?

The MG man would not be carrying the stinger, someone else would, as he already has the machine gun and ammunition with him. And I supposed an AK-101 with 60 round mag could get the job done and would definitely be cheaper, but it would be less accurate because of the higher recoil.

[Aqizithiuda]

finally, HurrDurr DumbFutur series is complete! remember they are intended to be used in the universe of this thing., which is kinda like this.

DISCLAIMER: this has nothing to do with my nation, i made them for a contest in DevArt, but i suppose they are relevant to notMMW, aren't they?

in the middle of the 2142 cold war, where almost everything was frozen, leaving only former deserts as agriculturally productive areas, and the PAC attacked the EU for resources, there was an untold story; battles were also happening in south america. the northeastern region of Brazil, a former semi-desertic area, was now ideal for production, and Chile had the Atacama desert, also fit for production. as such, the other starving nations of south america created the ULA (Unión Latino-Americana, or Latino-American Union).

the ULA first attempted to invade Chile; however, natural barriers such as the Andes made an invasion impossible. as such, they moved on to attack Brazil.

the ULA quickly allied itself to the PAC, aquiring weaponry and vehicles. meanwhile, Brazil used nationally-made weapons, as will be described now. please note that 2142 weaponry is much shorter and more compact to emphasize hi-speed low-drag.

Do you mind if I run this through LoadAmmo? It's a commercial, slightly modified version of the Powley computer that can accurately estimate case capacity, and it has a wider range of powders. I'd just need the bullet lengths and I could crunch the numbers.

Anyways, a couple of questions regarding autocannons:

I'm set on making them self-powered (for a number of reasons, e.g. : use where electricity is not available, as a backup if electricity goes out, etc.) . But I'd also like to be able to electrically power them (because that brings it's own set of advantages) . As such, what would be the best type of self-powered action that 1) could either be turned off or would not interfere with the externally powered operation of the gun 2) would be suitable for use with large cartridges (20-45mm caliber) and 3) if turned off, could be easily and quickly turned back on (switched back to self-powered operation) .

At first glance, a type of gas operation (whatever would be best suited) would be the winner as it can easily be turned off by shutting off the gas valve and, if used in a powered mount, could easily be turned back on by opening up the same valve, if the electrical system were to fail. Idk how well it works with such large cartridges though.

What sort of gas operation do the Russian ACs use? Long stroke piston? DI? The 20mm Oerlikon and 40mm Bofors use blowback, but you can't really "switch" that off and I guess it'd interfere with electrical operation (and negate its' advantages) ?

What type of operation did the 60mm HVMS and 75mm ARES use? Were they electrically powered?

I really don't think you can combine self powered guns with electrical powered guns.

Russian autocannons are probably long stroke.

The 60mm HVMS and 75mm ARES would both have used recoil operation for their guns, and electricity for their autoloaders.

How does linkless feed and dual feed work?

Some questions regarding dual feed:

1. Does it fire one cartridge from one belt and the next cartridge from the other belt? Or what?
2. Would a dual feed gun work with a single belt?
3. Is there any RL system that allows you to choose which belt you fire from?
4. Can single-feed guns be ambidextrous-fed (able to feed from the left or the right side of the weapon), without changing the receiver ( for dual-gun mounts and the like ) ?
5. Would a dual-feed receiver be significantly heavier than a single-feed receiver?
6. Does dual-feed work with a revolver or rotary cannon?

Read this: http://www.ibiblio.org/hyperwar/USN/ref/MG/V/MG-V5.pdf (warning: 120mb download). It will explain all sorts of things, including linkless feed.

1) no, it fires from one belt at a time.
2) why wouldn't it?
3) yes.
4) yes.
5) no
6) no idea.

Why not just use an RPK in 5.56 NATO?

http://www.atlanticfirearms.com/compone ... l?Itemid=0

Another good idea that failed to enter my mind. But, when you think about it, the RPK is outdated, and I'm trying to use firearms from the 90s or later. The RPK was made in the early 60s, and it's variants are mainly from the 70s. The newest and oldest Vepr variants use slant back receivers and cannot use most Ak mags or most other accessories, which would increases costs. Buying the middle variants of Vepr would be costly and confusing, and the Vepr rifles are for civilians, so they don't hold up to all of the military standards. The M27 IAR & Ak-101 are military weapons and both are smaller, lighter, and generally more mobile than the RPK or it's Vepr standards.

The RPK-74 was updated in the 1990s to meet AK-74M/AK-100-series specs. Also: I'm not surprised the VEPRs use slant-back receivers and proprietary magazines considering they are civilian-only models, as mentioned. I never said to use the VEPR, I simply posted one for reference and made sure to state that it was, in fact, a civilian firearm.

If you feel the RPK in 5.56 will not work because it was made in the early 1960s, boy do I have some information for you about the AK-100-series' receiver and the M16. The RPK is as viable today as it ever was, and I'd imagine that's why Russia still uses them. If you really want to make your own IAR out of an AK-102, for whatever reason, why not just go all-out and issue an AK-108 with a casket magazine and '100-series bipod?

[Fordorsia]

7.65x50mm NotRPK y/n? I am yet to combine one of my favorite firearms with my standard cartridge.

Seeing as though GPMG's were used in place of LMG's after the 7.65x50mm was introduced, what could it be classed as if it were adopted? If it wouldn't have a place, I'll just make it as another obscure weapon.

[The Archangel Conglomerate]

The MG man would not be carrying the stinger, someone else would, as he already has the machine gun and ammunition with him.

Ah, I see. I'm sorry, it looked to me as though you were saying that MG man would be carrying one or the other as secondary.

And I supposed an AK-101 with 60 round mag could get the job done and would definitely be cheaper, but it would be less accurate because of the higher recoil.

Eh. It shouldn't be too much an issue.

What I would need for my LMG class is a 5.56x45mm firing, AK-style, bipod equipped, 60 round Light Machine gun that has better accuracy than the AK & RPK series, but the maintains their reliability and stamina and has a good range. Does anyone have any good ideas, or can I just make a new gun that fits these modifications?
