".17 BMG has some incredible velocity performance, although its pressures are a bit high. Barrel / action life expectancy is about 1 round. The V-Max bullets go incandescent immediately out of the barrel and most of the energy is converted from kinetic to light and heat. Remote fire control system is highly recommended."

Do you suppose that if such a cartridge were actually fired that it would blow the action up instead?

One could be designed not to.

With the correct type and charge of powder, you could probably safely get close to 5000fps.

With the wrong powder type or charge you would obviously create a hand grenade.

The barrel would be the diameter of a sewer pipe. at such insane velocity the projectile might actually disintegrate.

Not really, but you might need a barrel at least 32ft long and powder that burns slower than tequila.

I wonder how fast a .17 projectile would go with a .50 BMG powder charge behind it? I question if it could even hold together down the bore.
The throat erosion would be extreme, that's for sure.

Wait!!! This is a great opportunity!!! Get this round on the radar of all Demo candidates and their surrogates as quick as we can; the scary factor of a gajillion FPS projectile should drive them to new heights of insanity!!!

I want to see someone actually make one and fire one. I wanna see what happens.

What happens? that imaginary cartridge is so overbored that becomes literally a boomb wiht a little valve. It is BS in other words.

The thing is one doesn't need to do something very special to achieve amazing speeds.
Many companies and individuals have researched hyper speed cartriges and always ran in the same problems.
For rifles the main limitation starts with the bullets themselves because as one passes Mach 4 bullets start to disintegrate so they
must be built of different materials and design that might defeat the original purpose.
So this is great for military / penetration but then no bullet will be able to compete in range with something self propelled with
explosive attached to it.

Weatherby actually did a lot of testing for himself and for the Army. He necked the 378 down to 30 cal and use something like a 60gr
solid or something like that to hit 5k fps.

In reality it is not that complex and you can take your 308, buy some sabots for 22 cal, buy a few 45gr bullets (something not too thin
of a jacket ) and then let it rip with some faster powers. w/o any special equipment you will be hitting the 4500fps soon although accuracy
will not be that great.

That is why the make varmint cartriges and rifles. longer 27" barrels and something like the 204 ruger that will put a little pill to 4.5k fps.

Perhaps the fastest will be the 17 remington but in terms of popularity will be the 220 swift that perhaps at some point had the largest
assortment of fast rounds.

But a lot 22 calibers will do including the 223 WSM and a few others.

By increasing the case capacity or reducing the bore and weight one doesn't get faster w/o substantially increasing the lenght of the barrel
to the point that is not feasible in a rifle anymore or to require powders that are not available for anyone commercially.

One can complicate things A LOT to squeeze only a few fps and to find out the bullets explode due to the speed anyway.

Same reason military planes cannot go over mach 3 or 4 w/o huge problems and melting in flight and thefore they have no use other
than curiosity and research.

In order to hit massive speeds the answer is in electricity and magnetism that is what the navy has been doing with rail guns, sabots
and solid tungsten projectiles. Everything else around cartridges past certain speeds is a waste of time.

I enjoy watching things blow up.

All jokes aside, it’s quickly becoming obsolete. Less and less pistols are made in ACP and less and less people pick them when choosing a caliber.

I give it another 20 years and it’ll become like .45 long colt for revolvers that got beat due to the popularity of the .38/.357.

No longer Secret, thanks DR. Evil
I don't think it will become all that obsolete anytime soon.

Every major manufacturer is still producing them.

The 45ACP is still as popular as the 9mm.

I will say though, I think the 40 caliber will be a thing of the past before the 45 goes away.

There has been some great advancements in other calibers that I see becoming more popular.

You can get hyper velocity without electricity.

Light-gas gun - Wikipedia

23,000 fps on gunpowder. NASA has a range of then from .17 cal up to 38mm. There are plenty of others out there too, some quite a bit bigger than that.
