When will firearm metals be upgraded?

[ziconceo]

I've made ones as strong as a 45 and Railguns that are super-sonic. Its not hard.

Power is only part of the problem. In coilguns you need a strong magnetic field, this is a combination of both power and the scale of the coils. That can be described as power and length of total wiring making up the coils. In the case of copper that is "unavoidable weight" and size. You can use finer wire and more current but you hit thermal load problems where you melt your coil packs with one shot.

Small lightweight designs are out there already, they are even quite energy efficient, but they require the use of superconductors with their associated cooling needs, which is the same kind of cooling needs needed in fine-wire high current conventional coil packs to keep them from melting.

Railguns still suffer from self-destruction and heavy rail erosion. The navy's railgun needs a new barrel after just about every shot still. If you've ever seen test firings and say, naww they are using conventional ballistics because of the huge muzzle flash and the fire leaking from every part of the barrel that is distorted and nearly flying apart with the shot. Nope, that is just high energy plasma generated by the railgun as part of it's firing. Which kind of goes back to the experiments in plasma powered guns where they worked on developing a propellant that would generate more power than modern gunpowders. The barrel pressures and plasma at those energy levels eroded the barrels too much. The idea was scrapped. The lower energy plasma that is the expanding gas in conventional firearms in certain rifles is already energetic enough to erode the hell out of the throat, you can imagine what happens when you step that up a few notches. Imagine the ignition energy being enough to melt the brass in the chamber kind of heat.

Practical arms are still sci-fi in the sense of being able to replace current types of firearms. The science behind them is simple and settled and experimentally they are quite easy to make both effective and functional but production ready and general deployment? Unlikely.

What's your opinion on a s-64 sky crane mounted 15,000 pound infrared death laser?

Our legislature feels the need to change our metallurgy, too. They wish all our firearms metal to be unobtanium.

And to people who say you can't get high velocity without recoil look up a diagram on how are recoilless rifle works.
it's really pretty interesting,
or at least I thought so.

all you have to figure out is how to direct an amount of gas pressure backwards as the bullet goes forward, which I admit isn't going to be easy from a pistol.

But that's just one way to do it.

You're going to get that mechanism in a snubbie?

[russ69]

We've been using relatively the same metals in gun barrels for decades...

There is a reason for most of the material choices we use right now. Good engineering reasons. Rifle cartridges work in the 60,000 psi range. We can work at higher pressures than that but would you buy a rifle that costs 5,000 dollars to build and uses rounds that are 30 dollars each due to the cost of materials and the difficulties in manufacturing?

Using "Time And Relative Dimension In Space" technology.
AKA "It's bigger on the inside."

A snub nosed 38 shooting a ss round at two thousand fps would exceed every pressure max out there. What happens when these rounds get fed into regular guns that were not built for them. Several lawsuits for missing fingers, hands, or eyes would put an end to that dream. There are plenty of uncomfortable guns to shoot out there already if that's what you want and they won't maim you. Not sure why you want the abuse but to each his own.

[Barbarosa]

Wouldn't be available in CA even if they were made. That whole "Roster" thing.

We've been using relatively the same metals in gun barrels for decades. It seems like there would be something better out there. Especially for pistols, most snub nosed pistols provide very low velocities due to the short barrel.

I was thinking we should be shooting stainless steel bullets with fracture points for HD rounds.

Problem is that our barrel steel is too weak for that.

But imagine how cool it would be to have a snub nosed 38 obtain 2000Fps!

Guns would be a lot safer too.

Just thinking out loud. Anyone see any problems with this? Besides over penetration [emoji14]

BTW, I know the costs and tooling would be expensive. But having a powerful pocket carry 25 acp would be pretty cool!

Not worried about legalities. Just a random thought. That law is really stupid because a ton of Nazi 9mm was iron cored.

Those rounds had a sintered iron core and were not solid steel. Not true solid core machined projectiles.

Make some titanium projectiles. Why go low tech with stainless steel?

Lehigh has been selling these for quite some time now,

Underwood sells them in their own line also. Wonder how they've had no problem as the statute seems to imply they would.

Haha too light. Though, titanium is brittle right? What about a titanium case (easy fragmenting) with a tungsten core (weight)

[joepamjohn]

Cost more than anything. Retooling for different metals is enough that most major manufacturers won't bother.

Also, the harder the metal, the more brittle it is, so lifespan and durability would come into play.

They really should consider alternative metals so when the confiscated guns get melted down they can have more uses than just manhole covers.
