Does a man-portable railgun firing 150 gram slugs at 10,000m/sec make sense?

(looks similar to this except with a longer barrel, less exposed hardware, and a larger scope)

This heavy gun functions as a heavy anti-material rifle for the Xenon Army it fires a 20mm, 150 gram hyper velocity tungsten slug at 10,000m/sec.

It has an effective range of 3000m and known to be extremely accurate.

Power is supplied to the weapon via a backpack power supply and ammunition is supplied by a 5 round detachable box magazine.

It is also relatively cheap and never jams.

The gun does have a few drawbacks mainly extreme recoil (still substantially less than a comparable primitive gunpowder firearm), excessive weight, and it at times has a few reliability issues mainly in the form of overheating after only a few shots, extreme rail wear causing rails to be needing replacement every 100-400 shots.

150 grams at 10 km/s?

That's in the same energy range as a 105mm gun.

A Mr. Newton would like a talk with you. Something about dislodged shoulders and shooters being splattered across the ground.

In a heavy support role, yes. Although I doubt it would be cheap. Also, you say it never jams, then say it has reliability issues. Could you clarify or was that an honest mistake?

I don't think a railgun should have problems with jamming but it does have reliability issues in the form of extreme overheating occuring after only a few shots, and extreme rail wear causing the rails needing to be replaced after every 100-400 shots.

As for the cost it should be a bit cheaper than something like a Javelin anti-tank missile launcher so its cheap for an anti-armor weapon but alot more expensive than let's say a rifle.

ideas on controlling railgun recoil? I heard railguns have less recoil than comparable conventional guns is this true?

[Sen]

Purpelia, it's less "dislodged shoulder" and more "oh god why did the gun just batter its way right through my shoulder and sever my arm despite being a blunt object" in terms of recoil.

Edit: yes, they do have less recoil than comparable guns. The problem is that, in this case, the comparable guns in question are 105mm tank cannon.

[Purpelia]

I heard railguns have less recoil than comparable conventional guns is this true?

That is a difficult question. How about you help me answer it? Start by reciting Newton's third law.

Okay 25 or 50 gram bullet then?

If you want my advice I'll give it to you. Forget bullet mass. Sure the mass is what kills but the shape is what gets it there. Hence what you want to do is take a real world weapon that does what you want yours to do. Than get the stats for the bullet it fires and the velocity at which it is fired. Basically, make an EM clone of a real gun. You can't go wrong with that. And if you want more power, just mix and match within reason.

[Imperial isa]

don't rail gun rounds still go by MMs then grams ?

[Former Wellboneland]

I need machineguns.

[Kouralia]

I need machineguns.

HMG - Everyone uses the M2 Browning (generally) because it's damned good
GPMG/MMG - I recommend the FN MAG (aka GPMG, Gimpy, L7 in British Service)
LMG - I recommend the MG4

That's my ideas, but I'm sure other people will disagree.

[Purpelia]

My advice.

Heavy: FN BRG-15 or anything soviet in 14.5x114
Medium/General: Any MG42 derivative or even the original. I would advise something like the MG 710 or MG3.
Light: Exactly the same as the medium.

What ever you do, stay away from Assault rifle cartridges for your machine guns. Be they 5.56 paintball or 7.62x39 they just don't mix with proper machine gun action. And anyone who says otherwise deserves to be shot, hung drawn and quartered by egregious amounts of 7.5 Swiss.

[Former Wellboneland]

Naaah, I need like Gatling guns.

I did a few calcs and if you want the energy of a 30mm API round and a velocity of 10km/sec you are looking at a 5 gram bullet and at 5km/sec you are looking at a 20gram bullet.

[Novariea]

Naaah, I need like Gatling guns.

I'm really not sure gatling/miniguns are a practical replacement for regular MGs. They're certainly not practical for infantry-level use, since they're going to be really heavy (the guns themselves AND all the additional ammo you're going to burn through in the same space of time).

I think you are missing the point. The mass of the projectile means nothing. It's the combination of shape (for flight trajectory and impact properties), mass and velocity that kills. What you want to do is take an actual 30mm shell, see how it's projectile is shaped and designed and than fire that same projectile out of an EM weapon. You can't just mix and match mass and energy like you do and expect results.

To give you a more down to earth example. What you are doing is taking a recipe for cookies that says: Bake for 1 hour at 100 degrees. And saying that if you bake it at 1000 degrees it should only take 6 minutes.

Don't forget batteries, minigun barrels don't spin themselves you know.

The gatling guns we have are hand-cranked and Saiyans carry them on Wilderness excursions.

Railguns typically aren't going to fire conventional bullets the projectile is going to be more like this:


mass gives it the energy needed to penetrate, and the shape helps ease penetration (long and thin optimal for penetration).

[Xenon]

In that case conventional machine guns are just better (faster firing rate, lighter, easier to use, probably more accurate, etc.)

Oh give me a break. Yes the rounds will be saboted. But the actual projectile can and will be anything you want it to be. Otherwise you are replacing your gun with a very inflexible system that can only fire kinetic projectiles. And given the other drawbacks or railguns that would just be a stupid decision to make.

Take a regular bullet or shell. Remove the projectile from the casing and put it in your sabot. And there is your railgun round.

Old but this makes S.N.I.P.E.R. the manufacturer of one of the first Assault Rifles.

(Emphasis mine)

Not really.
The Mini14 was in production from about 1973, so nearly 30 years after the MP-44 & SKS.
The AK, AR15/M16, FN CAL, vz52 & 58, Chinese Type 56 & 63, HK33, Galil, Beretta AR70, AR18, Stoner 63 series & Zastava M59/66 were all around before then.

I'm disapointed in you, Celtic Colonies. You started explaining assault rifles and a bunch of other stuff...

I hate to break it to you guys, but the Mini-14 is a carbine.

Anything chambered in 5.56mm, 5.45mm, 7.62x39mm, 5.8mm, etc. is a carbine.
