Pistols: Carbinzation

Image

In theory, a parabellum should reach and penetrate at four hundred metres, though outdoor environmental conditions, your hand eye coordination and ballistics, should make hitting a moving target a little iffy.

So in lieu of an actual carbine, you attach your pistol to a chassis, which stabilizes your aim, and you can add on all sorts of neat stuff.

Probably resolves the issue with automatic fire, as well, if your pistol has that option.

Speaking of which, how does a four millimetre slug cause massive trauma to an organic body?

Delivering kinetic energy to a body is never good for it. According to canon, a Gauss rifle launches a 4 gram, 4 mm slug at 1500 meters per second. That's twice the kinetic energy of an AK-47 round. If the round has the density of iron, it's about 4 cm long. As soon as it hits something, it will tumble or fragment; in either case it will deliver most of that kinetic energy to the organic body.

The part where canon is less credible is the assertion that the rounds have high armor penetration. There's a lot of energy there to crack armor, but that doesn't work very well if it hits armor designed to resist a 10:1 spin stabilized slug.

Penetrating armour might not be as issue, depending on the cap.

Still have to dump that energy into the target, not laser beam out the other side.

From what I heard from military surgeon trauma training a pig shot in the leg with a 5.56 mm assault rifle at short range died instantly. They could be revived by CPR though.

I've been told that if you're shot, you're out of action; considering we have accounts of the walking wounded fighting, I think that's temporary and not necessarily lethal, not wishing to test that theory on myself.

Is a twenty two long rifle lethal? Yes, depending on how you roll.

Referred to as a slide or bump fire, you add this to your semi automatic rifle or carbine, and you now have a full automatic weapon.

You turn a screw to make it float, and the recoil will continuously force your finger to press the trigger.

This is very useful, in jurisdictions where automatic weapons are controlled or illegal.

Haven't seen one for shotguns, but you could have one for a pistol, if you add on a stock or a chassis, which has the added benefit of stabilizing it.

gunshot effects could fill up a thread on it own...no gunshot is what you would call minor, bleeding, infection, tissue damage can add up pretty quickly. I have seen the evidence of a friend taking a .38 special to the chest, the bullet was a through and through he walked home and called the ambulance himself. There is a scar on his back, and a scar on his chest he was shot at pint blank from behind and walked away with nothing but a scar a short hospital stay and a good story to tell. The cashier at the next store fdown the road took a .25 ACP to te eye, destroyed te eye, but the bullet stopped against the bone at the back of the eye socket.

A third fellow shot by the police less tan half a mile from my house had six bulets in him fro a shootign the night before....he was killed by a load 12guage shot from a sheriff's deputy.

On the other hand, there are reliable accounts of a person being killed by a .22short, which is a particularly small round...a single projectile hit a major blood vessel and they bleed out in minutes. the .45ACP was adopted due to the low stopping power of the standard issue pistols used by American troops in the Philippines during an uprising. If stores are to be believed rebels would take multie shots fro the gun and keep charging..they wre dead on ehr feet but the trauma wasn't enough to actually disable them.

ON Medal of honor winner was fatally injured by .30 caliber and 20mm fire, but crawled back to his guns and shot down an enemy fighter beforedying...He was dead on hsi feet, nearly totally disabled but continued to fight for a minute or two.

So long story short...Injuries form gunfire are dangerous at any level, but not always disabling, even if they are in fact lethal.

Tese thigs are basically just fancy toys to show off to yer friends or guys at the range.....There are several devices that allow a semi-automatic weapon to MIMIC full auto fire. Usually, they are of questionable effectiveness, and even more questionable legality. Te actual usefulness of a system like that is up to debate as well. In all honesty, Full auto fire is not that big of an advantage unless you are in some serious....stuff.... It would be easier, cheaper and less legally involved just to go by a semi auto shotgun and load buckshot You put more lead down range per second, and it costs a LOT less than a semiauto carbine and a fancy gizmo.

IN the US adding a stock to a pistol is a No-No, it can get you jail time if you dont have the right paperwork. You can get arm braces that fits to the weapon and wrap around your forearm, or follow some pretty convoluted rules to add a stock to CERTAIN pistols.

that was the worst MONTH in the cities long and 'interesting" history. Second behind the week that a certain Union General marched through and burning part of it to the ground. Which resulted in possibly one of the last combat fatalities of the civil war when a Confederate patrol ran into a regiment of Union infantry...and took a shot at them...It's part of what the British troops in the are called "the Hornets nest" one version of the origin for the nickname Tarheels comes fro a battle where somone noted that Troops from the area must have had "tar on their heels" the way they stood their ground. SO, yeah people seem to be a bit belligerent to put it politey.

That particular month had a week in which there were six robberies in six days ending up with one woman blind in one eye, and the owner of the bar( a nice quiet neighborhood place) I hung out at was shot and killed. My knowledge of the ins and outs of a firearm was purely inspired by self defense :(


If yer wondering where this little hellhole is....Go to a US map, find highway I-77 and highway I-40, where they cross is just about dead center of the city.... so there for a while back in the 80s drugs were flowing throughout the county pretty regularly..with all the accompanying problems. Its also near the area where NASCAR go its start, which is partly due to the number of guys who were running moonshine in the area....now its Moonshine and a certain Hemp product.

As regards to the Nineteen Eleven Semi Automatic, the forty five calibre was adopted as a manstopper.

The Moros were probably high on drugs, did have a death wish and bound up their body, I think to minimize blood loss, and revolvers run out of bullets pretty fast.

I read a statistic that you usually only fire twice during a home invasion, so unless some crazed berserker breaks down your door, you're probably good with a revolver.

For concealment you can add in a clip that allows an easy ride on your waistband, without a holster.

those clips are a handy addition. I always carried my .38 Special in my jacket pocket. (Yep I had a CCW so it was legal :D) if push came to shove I could always fire it while it was still in my pocket. And there is the extra benift that if someone said hand over yer wallet, reaching into your pocket to "get yer wallet" is not going to cause as much suspicion...

The big issue na game is that the low life thugs in most games re suicidally aggressive. In RL the suspicion that someone has a gun is enough to back off a punk, if the gun comes out most of the RL lowlifes make tracks PDQ. In a game if you can be built like a Linebacker, wearing yer Imperial Marine Veteran Jacket with an Imperial Cross for Valor pinned to it and whip out a .50 Cal hand cannon, the thug with his little body pistol and no armor will still shoot it out like it was the OK Corral.

Most PCS are armed for war even when they go out to grab a burger with the Guys. Their guns are tactically modified with every gizmo they can lay their hands on. A simple Snub pistol loaded with ball ammo would probably be overkill against a typical street thug. who has no real reason to risk his life for the walking around money a Traveller carries... First sight of a firearm and he'll happily run away and find a nice safe old lady to mug for her retirement stipend.

even an enforcer or hired muscle is gonna bug out the first sign of armed resistance. They aren't fanatics, they are basically higher paid thugs who want to be able to send their pay on something besides hospital bills and lawyers fees.

Speaking of snubs, how long is a ten millimetre round?

I can't think it requires much propellant.

Also, seems ideal to make a twelve gauge variant for a sawn off shotgun, because, no recoil.

I can't think it requires much propellant.
Per canon, the bullets are 7 grams. If they're lead cylinders, they're only about 7 mm long, but that's silly. A 10 mm lead sphere is about 7 grams also. A high explosive armor piercing (HEAP) round exists, and for the Munroe effect to work the projectile probably needs to be 3 cm or longer. A plain high explosive round would be about one gram per cm of length, or 7 cm for 7 grams. A tranquilizer round might be even longer.

Then there's the propellant part. Since it's TL8 and very low velocity, it's probably caseless, not that caseless says much about its length. Call it one cm?

Since the 7 grams could refer only to the slug round -- which is a pretty wimpy round, unlikely to penetrate even a stout motorcycle jacket -- the other rounds could have different masses. In that case, the HEAP round probably determines the standard round length, which probably needs to be 4 to 5 cm long.

Since the entire weapon is only 10 cm long, it would be a bit funny looking. The six shot revolver version would have a bulky cylinder: 3 cm diameter for the rounds themselves, plus 3 or 4 mm for the walls of the cylinders. The 20 shot combat version would be clumsy, with either a 20 cm in-line magazine or a 10 cm double column magazine and a thick grip. Then there's the submachinegun version, which can probably disable enemies with laughter as well as firepower.

Double stack, single would be for a concealed variant.

The bullets have to fit into the magazine, so if the length varies, you'd couldn't mix rounds.

Unless you treat round like a rifle grenade, and the bullet fires is a blank; but then the special round would be larger and bulkier. That won't work with a snub barrel, you'd have to attach a cup as well.

So the auto pistol shoots a nine millimetre ten gramme bullet at five hundred metres per second, being equivalent to a ten millimetre seven gramme bullet at one hundred fifty metres per second.

Here's a quick size comparison for typical bullets...10mm is not visibly much larger than a 9mm,
Image

Asnub pitol wud have odd dimensions but not particularly clumsy its short length to height would give it an odd balance.However the low recoil wouldnt cause a problem. a .4 pistol is around 10 cm tall and the magazine isn't much shorter ..so a 10cm double stack mag would only project slightly below the shooters hand.

the closest ral word versio of a snub I can iaginne is a Gyrojet. A 13mm gyro jet pistol was a bit awkward but that's more of a problem with the design the company went with. if the concept had been fully developed the design would have improved beyond the crude prototype/limited production stage.

Maybe the rifling is tighter, giving it more spin and to overcome increased resistance would need more propellant.

This probably requires someone with Profession/Gunsmith, to tinker with a pump action shotgun.

Once he has, you depress the trigger and slide the pump action continuously, causing the hammer to drop every time, and you have an automatish fire; it's referred to as slamfire.

Spacesuit

Image

New one from NASA

A few of the advances in the design:

Lighter and more flexible through use of advanced materials and new joint patterns
Helmet and visor incorporated into the suit instead of detachable
Touchscreen-sensitive gloves
Vents that allow astronauts to be cooler, but can still pressurize the suit immediately
The full suit, which includes an integrated shoe, weighs about 20 pounds with all its accessories – about 10 pounds lighter than the launch-and-entry suits worn by space shuttle astronauts.

The new Starliner suit's material lets water vapor pass out of the suit, away from the astronaut, but keeps air inside. That makes the suit cooler without sacrificing safety. Materials in the elbows and knees give astronauts more movement, too, while strategically located zippers allow them to adapt the suit's shape when standing or seated.

"The most important part is that the suit will keep you alive," astronaut Eric Boe said. "It is a lot lighter, more form-fitting and it's simpler, which is always a good thing. Complicated systems have more ways they can break, so simple is better on something like this."

Prove that anyone can be an astronaut.

The most important question being, does my ass look big in this?
