Infantry Discussion Thread, Mk. 8 Mod. 0 [No Kaiju]

[The Archangel Conglomerate]

That would make more sense. I just figured it's intended to be an infantry weapon since we're in the infantry thread.

In my experience, anything that can concievably used as a weapon goes on this thread. Regardless of intended role.

[Gallia-]

you should try it, or just try something to make the outline less sharp since as is it looks kind of "weird"

idk u look kinda weird

what with that pink face and trying to eat an iron ball or whatever

[Imperializt Russia]

I once scienced a browning auto-5 into scrap metal.

The church branded me a heretic and now im not allowed within city limits of Ogden, nor the great Salt Lake, and this guy named Graham keeps following me around.

I watched a man set fire to his AKS-74u kitbash furniture. He bumpfired to set it on fire.
Not really sure why he did it. Or why he filmed it, for that matter.

Can you science me some friends who actually have some free time so I'm not stuck in this dorm being a responsible student and doing my homework?

:<

that could be solved by a mixture of drinking and narcotics abuse

I'd just like to pretend to be responsible and point out that this did not help me when I tried it.

[Fordorsia]

Actually since it's an AT round I figured it would be solid AP.

A ww2 AP load woulnd't be too different in projectile weight or MV. It could be a bit bit heavier at say 420gram in hwihc a case a rough bit of abuse of the KE equation would give us a MV of about 950-980m/s

KE calc if you don't want to do maths for different loads:

But don't people here use maths and shit to work out how heavy their bullet is and how fast it goes? Isn't that how they work out the performance?

They do but its just really for fine tuning once you have a concept and some ball park data to play with.
They don't actually do much of the math they let the various website calls do the lifting.

With a drawing of your projectile you could easily recreate it in the Geoffrey kobe website and I'm sure aqui will have the density data to let it calculator an actual weight for you.

Of course a lot of the calcs are really for small arm rounds and some can weird or just refuse to play when it comes to cannon ammo.

If you want the precise details that's one thing but if you just want something ballpark to have a rough idea then you can just compare to existing stuff, it will be close enough.

what have i done

Rejoined the GPC ubermensch. Welcome back.

[Vancon]

Oh yeah, forgot to say. I picked up an SKS.

Who else here's got one? Anything I should know about?

[Husseinarti]

Oh yeah, forgot to say. I picked up an SKS.

Who else here's got one? Anything I should know about?

So you picked one up.

What did you do after you picked it up.

[Transvaal Vrystaat]

What did you do after you picked it up.

Hopefully he operated operationally, like an operator.

[Puzikas]

Oh yeah, forgot to say. I picked up an SKS.

Its a rifle

shoot 7.62x39 through it

dont slap crap on it

cosmoline removal

[Purpelia]

It is my understanding that it is tradition for users of 1950's rifles to accessorize them with as many expensive things as they can find and than post images of this.

[Vancon]

What did you do after you picked it up.

I bought it and 120 round of stronk.

There wasn't any operator, and nor will there be.

I mean in terms of where does is do poorly. For example, does the wood stock deteriorate over time significantly?

The only thing that I'm thinking of doing to it is giving the wood a nice varnish. Thoughts?

[Fordorsia]

So what should the back end of a 30mm AP projectile from WWI look like? I've googled it but I just get a big mess of different shells from what I assume are all different eras.

[Sevvania]

Oh yeah, forgot to say. I picked up an SKS.

Who else here's got one? Anything I should know about?

Non-detachable, detachable, or "duckbill" magazine?

Albanian ones are worth the most (iirc), Yugoslavian models don't have chrome barrels and have a gas cutoff valve, and Chinese models have spike bayonets. But some have blades.

SKS-M and I think SKS-D take AK mags but can't take clips.

I've got a Norinco "Paratrooper" carbine that takes duckbill mags. It's a little heavy, recoil is comparatively stout, and the trigger pull leaves a bit to be desired but it's a fine rifle.

what have i done

Absolutely everything wrong.

anyway this is like three years of time but it's a GPC so yes it's going to be fat

It doesn't have to be, you're just choosing to make it fat.

Powley doesn't work for anything beyond rifle rounds.

FWIW, I use Crook's method myself to work out grenade velocities.

well unf gpcs themselves are wrong so it fits the character of the idea then

perhaps i should have just drawn 5.56x45mm tho

Rejoined the GPC ubermensch. Welcome back.

no i just coloured a thing i drew like 3 years ago actually unf i never did change the 2015 back to 2012 so i can see the confusion

if i were going to draw it today i'd draw two cartridges: 7.62x51mm and 5.56x45mm, the real GPCs

e: ort maybe 6.5x55mm instead of 7.62mm if i were being super gay and contrarian

[Crookfur]

There wasn't really such a thing in existance in ww1. 30mm is very much a ww2 and post war calibre. For inspiration have a look at the arse end of the hitch kiss 25mm at gun projectiles or the projectiles from the 2pdr gun of awesome.

[Gallia-]

2 pdr is god's gift to the british army rly

remove bosche

6x42mm master race.

too late you put it out there

no backsies

On relfection it really doesn't mateer what you look at the rear of cannon projectiles are all pretty similar.Most of them just stop and have a flat base like this 6pdr:

http://www.bocn.co.uk/vbforum/attachments/IMG_0870.JPG

its bigger but the overall design of a shot round would be the same on msot small calibre weapons.There are sometiem crimp rigns and things but you get the general theme.

[Fordorsia]

Thanks.

What are those projectiles made of anyway? I assume that they don't just have copper jackets painted black or something, right?

[Crookfur]

Thanks.

solid steel in most cases likley with just the relevant coloured paint on them. no real jackets as the driving band gripped the rifling.
