Big bores

>>34871437
Smaller bores do everything better.
They're not as fun though.
>Tfw no 45-70 lever action

>>34871437
We haven't, it's just that everything past .50 is considered Artillery

>>34871437
Practicality of using smaller rifle rounds with higher velocity to do the same job. Larger rounds are generally better at punching through loose brush, but for solid armor a smaller round going faster is better.

>>34871437
can't get high velocity with BP, so you have to use a large diameter bullet to get any kind of decent range
with smokeless powder the velocity is the name of the game and more mass to push results in a harsher kick for what you're pushing out

>>34871437

Because velocity, range, accuracy, and capacity are much more important.

They haven't. The trend continues

Black powder could only push a bullet so fast and since F=MA if you couldn't get the velocity you compensate by using a bigger bullet.
But then smokeless powder came along which allowed for greater velocity and spitzer bullets were then made to take advantage of that thus making it advantageous to use smaller bullets for greater velocity.

Couldn't they just use more black powder ? But I suppose there is an hard limit on how fast an explosive can detonate ?

>>34871517
.500 Nitro Express ftw!

>>34871437
They had to use big bullets, because black powder is objectively bad.

>>34871437
.458 SOCOM, and yeah, anything bigger than half an inch (besides Shotgats iirc) is a Destructive Device and then the NFA lets the ATF stick their dicks in your butt

>>34871589
Also pressure.

>Couldn't they just use more black powder ? But I suppose there is an hard limit on how fast an explosive can detonate ?
Black powder and smokeless powder are not explosives. They're propellants. Explosives detonate very fast (kilometres per second) and the detonation propagates via a pressure wave (think speed of sound and sheeit), propellants burn (but they have their own oxygen source included so it's not like burning petrol or whatever) slowly and the burning is propagated via *heat flow*, not a shockwave.

This is why if you put funpowder on a table, you can easily light it and it just burns bright -- you need confinement for funpowder to burn very fast (otherwise the gas generated by burning will *push other grains of powder out of the way*).

>>34871437
While having a gun is infinitely better than not having one, when everyone has one the guy who has the greatest continuity of fire wins. As such, for people and the armor they carry, small, fast and most importantly light is the name of the game. We just didn't develop the technology that could meet this demand until roughly 200 years ago or so. We still use large diameter projectiles, they just have different applications that aren't limited to people. So .458 SOCOM can be shot out of an AR but it's primarily used for vehicles, 50 BMG was traditionally used for machine guns to be used on planes, trucks and people but now we use that for long range vehicle interdiction and hitting targets accurately through hardened cover as well. Really big shit (artillery) can be used for everything, but big enough artillery can be loaded with nuclear rounds, and those can do in literally anything. It's all about intended purpose.

tfw .45-70 lever action very soon

>>34871457
I though 20mm was the cutoff for arty, .50 was just an American thing.

I don't even like Lever gats and I knew they had em in .45-70...

>>34873126
cutoff is 14.5mm
15mm is where cannons start, mg151/15 to be exact

New technology or velocity

I hope the US military goes balls to the wall on their exoskeletons so we can make everything as high caliber as possible just because we can.

>>34873167
I think they were both talking about owning one, not about the existence of one.

>>34871437
When you have a single shot rifle, you need to make sure you take down the charging Zulu warrior with the first shot, because he'll be up in your face poking your with his big black spear before you can load another round.

When you've got an automatic rifle, you want to be able to carry the most ammo possible, so you can waste a hundred rounds firing blindly at Charlies in the trees.

KE=MV^2, V squared. Comprendre?

Come on now...

>>34872944
I think you may be conflating some ideas there. Smokeless is a propellant(iirc). BP is a low order explosive. Something with very high det speed would be a high order explosive like RDX. Or high explosive for short.

>>34873271
Exoskeletons most likely wont be weaponized to any significant degree. If you need heavier weapons than what one or a handful of dudes can carry, the guy carrying the radio will call someone with a plane or an artillery piece to help out. Same story with mechs. If we can make a mech do x, a tank with the mech's tech will be able to do x + all kinds of other shit and generally be more helpful.

>>34871437
F=M(V^2)

Doesnt need to be bigger, just faster

I think you've got the wrong post, I didn't address anything you just said.

Until we equip them with mini-reactors and laser tech, making them compact walking anti-missile systems. The future is going to be lit. Literally. A lightshow in the skies and the ground

So many assumptions

>>34873423
All that would be better on a tank. Faster, lower, more stable. Besides, anything that can kill the tank can kill the mech, but there are many things that can kill the mech but not the tank.

black powder has a logarithmic diminishing returns curve to velocity. you eventually reach a point where you add more powder and the bullet won't go any faster.

this is also why you can fill up a musket's barrel with black powder and it won't kaboom the barrel. though smokeless powders will.

On that note the only role I can see power armor in is as an in between an infantryman and IFV/tank for urban warfare and depending on how heavy that is, it would only be good for clearing the ground floor a building and support outside of it.

I'll be in my bunker, fingerfucking my Marlin 1895 SBL. Just a few more weeks till black bear opens...

>>34873608
What I've been saying for years.

IFV charging station that can quickly deploy 1-2 relatively heavily armored mechs for use against dug in opponents in an urban environment.

Just small enough to force themselves through the average doorway. Armored as much as possible, using LMGs, GPMGs, and/or a grenade launcher for primary weapons. Hermetically sealed to resist blasts or chem/bio weapons(such as CS gas). Electronics suite including a hud and shot-caller type system.

The point of mechs won't be replacing MBTs, It'll be to make being a tip of the spear door kicker safer.

See, this would make a good thread. We have had innumerable threads about how and why mecha can't replace MBTs, but how about a thread about how we can use contemporary examples of exoskeletons and "mobile suits" to augment the one place where all that technomagic would go to the best use; the door-kicker?

Groups of men with weapons have been kicking in doors to places with groups of men with weapons inside of them for thousands of years. It's never going to stop. The mark of advancement in technology, and thus war fighting capacity is not defined by the ability to eradicate cities, fleets in seconds. But the ability to kick in doors as efficiently and unfairly as possible. How can we make the door kicker the last person anyone on earth wants to fuck with in every conceivable situation and circumstance?
