40 USD per round
8000+ USD for the "rifle" depending on options.
Weight between 80 and 110 pounds depending on options.

Who would have the guts to shoot the damm thing?

Thus, they are largely "range queens"—rifles that are brought to the range for a fun time, but not usually used for hunting or other "more practical" uses. Additionally, the cost of owning and operating such a firearm is beyond most shooters; the rifles cost ~US$8,000, loaded cartridges are $40 each, and the individual lathe-turned bronze bullets are $10 apiece.[4]
Quote:

The cartridge propels its 3,600 gr (230 g) bullet at approximately 2,200 ft/s (670 m/s). This yields a muzzle energy of 38,685 ft·lbf (52,450 J)[1] and a momentum of 154.1 Newton-seconds. This kinetic energy would allow the .950 JDJ to pass through several body-armored humans. It is comparable to the original tank rounds of World War One in terms of ballistic energy.
By comparison, the 5.56x45 cartridge, used in the M16 rifle, produces between 1,200–1,300 ft·lbf (1,600–1,800 J), while the .308 Winchester, a favorite for hunters and medium-range police/military sniping, produces between 2,000–3,000 ft·lbf (2,700–4,100 J) depending on the load used. The ballistics of the .950 JDJ is more similar to that of the 20mm autocannon round, which delivers approximately 39,500 ft·lbf (53,600 J). The muzzle energy of the .950 JDJ is comparable to the kinetic energy of a 2,800 lb (1,300 kg) automobile traveling at 20 mph (32 km/h).
In a 110 lb (50 kg) rifle, this will develop well over 200 ft·lbf (270 J) of free recoil energy if an efficient muzzle brake is not used. This is far beyond the shoulder-firing capacity of nearly all humans, even without considering the difficulty of shouldering such a heavy rifle. Shooting is usually heavy "lead sled" or similar shooting rest, and the rifle is not held to the shoulder because of the severe recoil and possible injury. The rifle scope has significant eye relief to avoid injuring the ocular orbit.

Why would you shoot the damn thing ???

Because it's there?

Anyway, I'd shot my dad's rifle when I was a kid, at the Fish and Game, but this was totally new.

I shot at a can. I missed, many times.

Sorry, infi, we were distracted by the monster-gun.

.22 is ... well .. small. smallish.

Maybe you need a bigger can.

HungLikeJesus 11-11-2011 05:38 PM

First the box, now the can.

TheMercenary 11-12-2011 07:47 AM

Thanks F3 for that post. Makes more sense. No one can actually shoulder fire the weapon.

footfootfoot 11-12-2011 03:00 PM

I can imagine the whole equal and opposite reaction thing when half the reaction is travelling through several body armored bodies, but what I am not sure of is how to think of 200 ft pounds of energy. Is that the same a someone dropping 200 pounds from a height of one foot onto my shoulder? And is that the same as dropping one pound from 200 feet onto my shoulder?

In either case, no thanks.

Gravdigr 11-14-2011 12:43 PM

Damn, that's a lot of aluminum.

GunMaster357 11-14-2011 02:10 PM

How many beer cans ?

Gravdigr 11-16-2011 03:28 PM

A regular (relatively dry) aluminum beverage can weighs ~20 grams on my old, cheap recipe scale. Call it ¾-ounce, know what, just call it an ounce.

1 can = 1 oz.
16 cans = 1 pound
2000 lbs = 1 (short) ton
USS Independence LCS displacement = 2480 tons (average of 'light' & fully loaded displacement)
2480 tons = 4,960,000 lbs.
4,960,000 lbs x 16 cans to the pound = 79,360,000 regular aluminum beverage cans

79,360,000 aluminum beverage cans = 1 USS Independence

Did I do that right? It doesn't sound like enough cans...

GunMaster357 11-16-2011 04:09 PM

Yep. I believe you got it wrong. Displacement means the mass of water that is moved when the ship is floating in water. It is not the total mass of the ship. Also, displacement is measured in metric tons.

Back to the other end of the scale, here's a good improvisational weapon, to use on unwanted callers, like Baliffs, Police, Jehovah's Witlesses, Landlords etc. All you need, is to have a first floor window that opens above the front door. When you hear them knocking, quietly open the window, and drop a cat on their head. Film it for posterity.

You strike me as being that same guy who came around awhile ago talking about how viciously clever he was to the Panda Express employee.

Gravdigr 11-18-2011 03:44 PM

That "drop a cat on their head" bit might be useful, though.

Those things are a hell of a lot bigger than they look compared to those people standing next to them. That is a fish eye lens I think. That plane is huge.

xoxoxoBruce 12-01-2011 06:27 AM

For what the cost to buy and fly, they ought to be as big as Rhode Island.

Size ratio plane/people look OK for me.

That thing has a length of 146 ft after all.

ZenGum 12-01-2011 08:06 PM

Just wondering, if there was a fight between an M1 Abrams tank and an A-10 Thunderbolt (Warthog), which way should we bet?

I'm inclined to go for the Warthog - I imagine it swooping down and dropping bombs faster than the guns of the tank could track it.

TheMercenary 12-02-2011 07:34 AM

A-10 would win that one easily.

Are you kidding? Google up "tank killer". This is a tank's natural predator. The A-10 is my favorite warplane, by far.

Sounds like you and my son have been hanging out. Either that or your're 8.

ZenGum 12-02-2011 05:40 PM

Well, it's not like I was making sound effects as i imagined the battle. Much.

I was wondering because the Abrams is considered to be the toughest tank around at present. What if we limit the A-10 to only using its main gun, no rockets or bombs? Would that make it an even fight?

zippyt 12-02-2011 05:55 PM

Still no contest

ZenGum 12-02-2011 06:11 PM

Pilot has to keep one eye closed.

Any better?

zippyt 12-02-2011 06:39 PM

Not really
30mm of badness


regular.joe 12-02-2011 06:52 PM

Yea, the A-10 would eat the tanks lunch.

footfootfoot 12-03-2011 09:50 AM

Yeah, but what if the tanks had giant engines and wings and two 30mm canons and they one hundred million thousand billion feet per year?

Alright, guess who I sound like?

Wikipedia lists the A-10 at only $11.8 million each. In 1994 dollars.

ZenGum 12-03-2011 04:50 PM

From Foot's post:

Mustang carries maybe 700 kilos of munitions.

Thunderbolt carries up to 10,000 kilos.

Just a whole different league, really.

footfootfoot 12-03-2011 05:08 PM

Oh yeah. What is interesting is when you look at two similarly sized planes, with similar top speeds, despite one of them having fucking ginormous engines it makes you think "There must be some reason for that."

ch'yeah. 10,000 kilos of reasons

I heard the plane described as a canon with a plane attached to it.

someone figure out what the dollar equivalents would be.

xoxoxoBruce 12-04-2011 01:13 AM

The second engine is to keep the A-10 from flying backward when the cannon is firing. :speechls:

Merc, I made a mistake in that post. Grav caught it above.

My Google results had the F-22 Raptor stealth fighter jet mixed in with the A-10.
The F-22 costs are on the order of $150M each

TheMercenary 12-16-2011 02:18 PM

I was sort of yanking your chain. Hard to compare costs of something from 40's and 50's in cost to today in the more modern lethality of our combat environs. But I was a bit surprised to see how much slower it was. I have been on the ground when they have flown over at tree top level and I never heard them coming until it would have been to late, if I was a bad guy.

Gravdigr 01-12-2012 05:03 PM

It's been a while for a CoolWeapon, so...The F-35 undergoing the last of sea trials on the USS Wasp.



Let's see...one of our fellow Dwellars had a hand in developing some/one of the systems on the F-35 don't they?

glatt 01-13-2012 08:16 AM

I didn't know anything about the F-35. So it lands vertically and can take off without a catapult. Pretty impressive.

Can it take off vertically?

FloridaDragon 01-13-2012 06:49 PM

There are three variants ... the stovl (short take off and vertical landing) version that is shown in the video (the F-35B), the airforce version, the F-35A that is the ctol (conventional take off and landing) variant ...and the carrier varient, the F-35C ... which has stronger landing gear and a tail hook.

FloridaDragon 01-13-2012 07:02 PM

Short video of the stovl variant doing a take off ... love it when all the doors come open and the nozzle rotates... this is the test flight version with the side open doors ... the first production ones have the bigger single piece door that opens to the back to help airflow into the lift fan :
