[Nua Corda]

Same as the LSW, just minus the open bolt sear and casket mag. Add variable power 4x/8x optic.



Enough not to suggest some kind of SPIW grenade launcher thingy from your infinite patent bin?

Only if you want it .

I kid, I kid. Do you want a SPIW type GL?

Yes. I thought I would make two Grenadier models, one with a smaller caliber repeating launcher, and another with a single shot 40 mm version.

[Mozria]

Would 7.2 x 48 mm cartridge work out? Of course, I would have to generate real cartridge specs and a projectile profile plus ballistic model to truly see, but could it be a good idea?

If you were aiming for a GP round like .280 British or 7mm UIAC, yeah. Or if you kept the OAL under 65mm.

Well, I do want my rifles and GPMGs to be able to share ammunition. With a cartridge like that, I presume it would be doable. However, I can't stand but to think it underpowered.

If you are worried about being "underpowered", just play in the 1870s-1890s, rock a 10mm Jarmann chambered rifle, a hotchkiss crank-repeater or a gardner gun. Presto, problem solved.


Please don't take that as "snappy" or sarcastic, but Corda, Aqiz and Prem may be your best bets in regard to towing the "kinda-sorta in-between cartridge" line.

Power isn't really a concern. You want to keep a person's head down, or put him out of the fight, not blow him in half. Actually, wounding is better than killing, since it forces the enemy to deal with the wounded man.

Instead of a barrel and separate grenade. It's basically what the later AAI SPIW used.

Issue the 8mm Mauser, M1 loading of the .30-06 or the .276 Enfield.

Alternatively, as Galla pointed out, there's 6.5mm Krag, and 7.5 GP11

[Rich and Corporations]

Hmm.
Carbine and general infantry round: .30 carbine necked down to 6mm
MMG and sniper round: 7mm remington

[Mozria]

I guess I could make the 7.2 x 48 mm round work. It just seems that it would be in some silly twilight between intermediate and full rifle cartridges. I don't like that reality, but it would certainly simplify logistics.

[Aqizithiuda]

Hmm.

What bullet weight, OAL and barrel length for the .30/6?

[Nua Corda]

So, basically just the firing mechanism and magazine, with the cases serving as the barrel(s)?

Pretty much. The mag isn't so much a mag as a guide rail and spring that holds the rounds in position/pushes them up.

Seems like that would leave the rounds and mechanism a bit vulnerable...

[Rich and Corporations]

What bullet weight, OAL and barrel length for the .30/6?

bullet weight: 4.1 grams (low-lead FMJ), 4.8 grams (AP-lead boat tail tracer)
OAL: 43mm
barrel length: 5 inches or 15 inches
pressure: 55,000 psi


as a minor note, the .380 acp subsonic is also used for special operations

[Black Hand]

If I have power armor should I have IFV's or no? Mean they can't walk everywhere but air transport should.be viable within controlled areas or alternatively trucks. But I am unsure on APC's and IFV's

engines typically are more efficient the larger they are, and power armor is usually depicted as using either microturbines or batteries, which is pretty fuel inefficient.

[Romic]

Depends do you want more than one in one vehicle? Or do you want it as an entrance/extract vehicle?

If entrance/Extract IFV with a squad of soldiers if big enough so you can get a good ammount of firepower in one position.

APC if you have multiple Power suits to go (mostly because of the larger troop compartment)

or if you are really daring use both

EDIT: You could also send more regular troops with APC also. The armor of an APC would benifit so if it's going in heavy combat it just can't be taken out and then you loose lots of money and men if a couple hits.

Probably. But, hey, it's lightweight .

bullet weight: 4.1 grams (low-lead FMJ), 4.8 grams (AP-lead boat tail tracer)
OAL: 43mm
barrel length: 5 inches or 15 inches
pressure: 55,000 psi


as a minor note, the .380 acp subsonic is also used for special operations

A rough estimate, based off the 6mm Garin, suggests a MV of 2460 ft/s from a 15" barrel for the 4.1 gram bullet. The trajectory would probably look a bit like this: http://www.geoffrey-kolbe.com/cgi-bin/t ... age=884420

From a 5" barrel, you're looking at around 2000 ft/s.

[Lossesin]

LAR-89MBRS is the standard Military Weapon for the Lossesinic Military and also works as a Swuad Automatic Weapon and a Designated Marksmen Rifle on top of its main role as the Standard Battle Rifle of the Lossesinic Military.

Wasn't there another design that had a fixed mag which swung forward to be loaded with stripper clips?

Not for any grenade launcher I remember.

Model 1790 Wall Musket

Cartridge: N/A

Caliber: 25.4mm / 1.

Effective Range: 100 meters

Maximum Range: 180 meters

Rate of Fire: N/A

Feed System: Muzzle Loading

Bought as a pair in 1790 by the Fordorsian Militia, the Model 1790 was among the largest muzzle-loading black powder firearms ever made. The muskets were designed to counter the increasing number of large Wasters strapping their smaller kin to thick wooden shields, allowing them to cross the Silver Wind bridge in relative safety. These shields proved to be effective against the mismatched and varying caliber muskets of the Militia, and since much of the Militia's equipment was bought by those serving, many were forced to chip in to afford the Model 1790's.
Starting as a smoothbore musket firing round lead balls, the Model 1790 was relatively inaccurate despite it's extremely long barrel. The round ball was still very effective against the Wasters' shields whenever it hit, punching through all their layers and into the individual holding it, usually completely destroying whatever body part it hit.
In 1802 after the invention of the Minnie ball, both muskets were converted, replacing their smoothbore barrels with rifled ones, making them much more accurate at longer ranges.
Both rifles saw use at the Silver Wind bridge for a further 30 years before being taken out of service. Both rifles still survive and are on display at the Fordorsian National Museum.

Why is it so advanced? Is your calendar different?

RL has you beat, of course. Jingals have been popularized by forgottenweapons or whatever, but they pale in comparison to European giant guns.

[Bezombia]

I present

The Fishgun 9000

(actually called the XM6A3E1)

Essentially designed to bring 7.62x32 to a full sized carbine, specifically for the civilian market, the XM6A3E1 is a modified M6A3 with a longer barrel, fixed stock, and full length handguard. While it is possible to make a pseudoXM6A3E1 by giving a normal M6A3 the barrel and stock of the E1, the handguards are not interchangeable. Fire selector stands for "Flounder" and "Salmon".

Now with Uberbreak

That, combined with the relatively long bolt travel, straight-line layout and FG42-style buffer should make felt recoil negligible, especially with an intermediate.

I like it.

It's ugly, but in an exotic and functional sort of way, like the Bren for instance.

[Bezombia]

Guys, I am trying to embrace smaller calibers than my previous super-recoiling rape-train round, but it's really hard. How does 8.25 x 55 mm sound to you?

That's not a small caliber, that's a sniper cartridge at best, and even then seems a bit overpowered for the role.
