Is there a practical difference between 5.45x39 and 5.56x45?

Also, woo, this is the 7000th post anyone has made on this thread.

Yes. The 5.45x39mm is easier to extract in adverse conditions, the 7N6 projectile has more consistent terminal effects than the SS109, and the 7N10 should have better penetrations than the M855A1

[Arkandros]

I was thinking the other day, what would be the best exterior plating for my soldiers power armor? I'm thinking a IR diffusing shell for standard infantry armor, with a RAM coating and greater IR diffusion on Special forces and reconnaissance models. maybe forgoing any stealth on the amphibious assault armor and simply electroplating aluminum and anodizing it for ultimate weather resistance.

also a proposal, so a dome shaped explosive charge with deep cones cut into the surface and then lined with copper to make an anti vehicle charge, rather than attempting a single armor defeat. part of this is also to maintain some effectiveness against infantry. and the armor penetration is sometimes necessary given what my opponents field infantry wise.

Personally, I would suggest using non-Newtonian materials, particularly shear thickening materials, like oobleck. Shear thickening materials are defined by their increased strength and rigidity under stress, not consistent with standard Newtonian mechanics. It would allow for free motion, while still protecting against impacts in a fashion similar to plate armor. Combine this with the properties of silicone polymers (Polydimethylsiloxane (PDMS), for example, which gives silly putty it's anomalous properties of being able to ooze, bounce, or shatter) and you could construct a material with impact properties analogous to ceramic plates, while simultaneously self-repairing/reconstructing.

Thought it might be appropriate to post it here. Cheers, comrades.

That's a mildly interesting gas layout. It's certainly not AR-15 standard.

Well, I find the 6.8 to be the perfect balance between stability and stopping power.

...okay...

but what about the gas system

[Swedish Democratic Republic]

I am looking to evaluate possible replacements for the V1M Sniper rifle. Bring forth your designs.

Criteria: Semi-Automatic, 7.85x57mm, Ability to mount bayonet, Must have the ability to mount a bipod, Backup iron sights, Ability to attach several types of optics, Ability to attach supressor.

The design chosen will be designated the V2 Sniper Rifle.

7.85x57? Is that a proprietary cartridge of your design?

[Imperializt Russia]

Bore out the Dragunov sniper rifle.

Is there a practical difference between 5.45x39 and 5.56x45?

Also, woo, this is the 7000th post anyone has made on this thread.

How do you mean, "practical"?
They're of completely different designs suiting completely different weapons for different reasons and are not interchangeable cartridges.

It is the standard cartridge used in our battlerifles, So yes.

Any reason you aren't using 7.92x57mm?

[Ea90]

Or at least we can utilize said remark to summarize Benos' obsession with everything that is an over-hyped, over-publicized polymer brick with a trigger.

My favourite post of this thread so far.

Yes. The 5.45x39mm is easier to extract in adverse conditions, the 7N6 projectile has more consistent terminal effects than the SS109, and the 7N10 should have better penetrations than the M855A1

Wouldn't it be fairer to compare the 7N10 and M995?

[Purpelia]

Bullet design question time. I have been told that my boat tail angle should not be less than 7 degrees, but is there a maximum value as well?

[Arkandros]

can I get some measurements on an assault rifle (say, 16 inch barrel) for the:
Width of the rifle receiver?
Stock length?
Receiver length/width/depth?
Height of pistol grip?
Diameter (or height) of foregrip?
I'm assuming the foregrip length would scale depending on barrel length. If that's wrong, please correct me.

Guess I just never thought of it at the time. I Guess it is to late for a caliber change now though, Considering 12 million rifles as well as machine guns in this caliber have already been manufactured and we believe in sharing amunition between most of our weaponry.

You're going to have to be more specific than just "an assault rifle".

Eh..... Bullets and guns to be used on planes by US Air Marshal-type people, gogogo!

shorty FALs laoded with M993 ammo of coruse







or if you must be boring and practical a concealable semi auto pistol with a good hollow point round.

Bora-Acorn M104 Gladius
Firing the specially-designed 7.62mm LVS-A round, the Gladius is built for shipboard [NB: same kind of environment as on a plane] combat. With a compact weapon and low-velocity slug rounds, this is a package that brings everything you need to fight off criminals without spacing yourself.

The M104 is typically used by ship crews, and Safeguard teams assigned to known piracy hotspots.
The 7.62mm LVS-A round is short and slow, but packs enough weight to give even the toughest of augmented hijackers a black eye.

the barrel appears to be above the ejection porn
this bad, bad, bad

Yes.

And that value would be?

I'm not entirely certain the 7N10 is an "armour piercing cartridge" in quite the same vein as M995 is.

[Bezombia]

Yes.

And that value would be?

I don't know what it is. I just know that it exists.


I DO know that the base should be absolutely no less than 0.65x the bullet diameter, so that might be something to go off of.
