Oh that is just pure AWESOME! I wonder what would happen if you placed a flechette instead of a 22 cal bullet? It should keep some awesome ballistics for a very, very good range.

I think the way it works is you point the bullet away from your target and loosely hold the rifle as you pull the trigger. The rifle will fly out of your hands and incapacitate your target.

Something like that.

Wow. Just…. wow. Imagine saboting a .17 Fireball out of that….

I imagine barrel life is about 3-5 rounds? Maybe they have to have a sequential series of progressively larger bullets as the bore is worn away (a’la the Paris gun).

The Wiki info is great … 50gr bullet in front of 105gr of powder for 4600fps.

Or you could just use, say, a .220 Swift… same bullet weight at 3900fps … but whatever makes ya happy!

the whole point was to break a world record of 5,000 FPS

the .22 Eargesplitten Loudenboomer, by it’s very name, should tell that it was never going to be a serious cartridge beyond the novelty of slapping a .22 on a .375

@Solomon:

*rolls eyes* Everything you learned about ballistics was in a movie theater, right?

flechettes are failures.

4600 FPS = 3136 MPH

Now, be nice. Flechettes aren’t a total failure. You pack a couple hundred of them into an atrillery or tank main gun round, and they do just fine. {grin}

On the 1911TechTalk Yahoo! list we were speculating about a .50 BMG necked down to .22, but the List owner, Geoff, came back with (IIRC) a 25mm necked down the phonograph needle.

Assuming you can even find one these days… (Bonus! diamond tip!)

What would be the point? It seems to me that the only point of this cartridge was to try to set a velocity record. In the end you still have an extremely light bullet (so low energy) with a low ballistic coefficient (so it loses velocity, and trajectory, quickly). There’s probably a good reason that cartridges like this one, or like a .50 BMG necked to .22, don’t exist in the mainstream – they’re pretty pointless, except as interesting curiosities. Bullet energy may increase with the square of velocity, but that means that the force of air resistance does also. There are much better bullets, with higher ballistic coefficients, than an ultra-high velocity .22 that have a flatter trajectory and higher energy at long ranges – put the numbers for this round into a ballistic calculator and it’s not that impressive at long distance; you could never make a shot like the ones recently made in AFG with .338 Lapua. And a .378 case necked down to fire a .22 isn’t going to produce any less recoil than the original round, right? It’s still (if it has the same powder load) putting the same amount of energy out the barrel (theoretically) and must have the same opposite recoil reaction, right? (I’m no physicist, but it would seem that way to me.)

C’mon, 120mm Rheinmetall tank cannon round with a sabot — that’s already 5200fps. Sabot diameter is about 25mm.

Necked down to .224? :)

Geodkyt May 12, 2010 at 08:58 am

Heh. The bullet would weigh less than the sabot — probably stick to it instead of seperating cleanly. {snicker}

It’s called the .22 Eargesplitten Loudenboomer, only because the “.22 Holy Thundering Shit!!” and the “.22 BlowUpYerGun”
apparently were not descriptive enough, and the “.22 What The F**K Were You Thinking?!” was considered to be just a little bit off color for the time.

*snickerchortlecoughchuckle*

I’m sorry, was that in questionable taste?

It most likely detonates mid air a few hundred yards out from increased friction!
