[United states of brazilian nations]

Just spent ages trying to get the shading down on a pistol that's essentially the PX4 Storm with a squared off slide, thinking I was being vaguely original.

Then I realised the PX4 Nano is exactly that.

FUCK.

i did draw some concepts that, while not really inspired by any pistol and just freehanded based on my aesthetic preferences while keeping a fairly basic layout, it does resembles the PX4 just a little bit.

but yeah, it sucks when you have an idea and realize that someone already made it IRL. happened to me when i had the i-thought-it-was-original 5-man fireteam, 10-man squad idea, to be greeted by the germans knocking on my door and asking to have their Jäger squad back.

[The Archangel Conglomerate]

I say 9.5-12gr/.64-.84cm³. I'm probably a bit off though.

That explains a goodly bit. Good to know my 10,3gr estimate wasn't too far off.

[EsToVnIa]

.30 Carbine and .357 Magnum are very, very similar out of an 18" barrel.

I wouldn't have figured the Tree-fiddy-sevn for grenade launching either, to be fair.

Tbf, the M2s are chambered in 7x35mm rather than 7.62x32mm

You are upset to find out your ideas are shared by professionals who actually do this for a living?

I don't see any issue with kitbashing and general use of RL designs as a basis for my stuff. Infact I sometimes blatantly copy them

Nog een vraag!
Why were the MKR cartridges so tapered? Was it to help with the extraction of high pressure cartridges from a straight blowback weapon?

[Reikgard]

Latest version of the WG 8mm (Wid Gevar = Self Loading Rifle)

Thoughts and suggestions appreciated

What lineart program do you use?

[EsToVnIa]

Pretty much what I do.

IIRC, it had to do with the cartridge being rimfire.

(To amend your earlier statement, the MKR wasn't blowback, but rather used a locked breech, vertical bolt mechanism)

I swear, last time I looked it up on World Guns it was blowback. He must have gotten some more info.

Anyway, based on concept drawings, I'd say that Prem's right about the case shape being rimfire related: http://i40.fastpic.ru/big/2012/0826/17/ ... 22a617.jpg

Yeah, I know what you mean, I checked it out and he added "locked breech, gas operated action with vertically tilting bolt."

Any idea how well the caseless concept would do?

[The Archangel Conglomerate]

#IIRC, it had to do with the cartridge being rimfire.

Weird. I suppose it makes sense. The ,303 has a fairly decent taper as well.

(To amend your earlier statement, the MKR wasn't blowback, but rather used a locked breech, vertical bolt mechanism)

Bastard. Last I checked, it was straight blowback.

Thanks for that.

Would I be wrong in thinking the paper claimed the rimmed cartridge did away with rim stacking issues?

Not particularly well, for the usual reasons.

If I were to change anything about the cartridge, it would be to make it a rimless rimfire: http://iaaforum.org/forum3/viewtopic.php?f=8&t=15223

I don't know. That's the only page which was posted: http://www.iaaforum.org/forum3/viewtopi ... =8&t=13300

You could email Maxim Popenker and ask full the full report if you're interested in learning more.

It was to keep the rims from catching on each other.

[The Archangel Conglomerate]

I don't know. That's the only page which was posted: http://www.iaaforum.org/forum3/viewtopi ... =8&t=13300

Interesting. I wonder if the guy claiming to have fired one is legit or not. A bit of information on the wounding and penetration

You could email Maxim Popenker and ask full the full report if you're interested in learning more.

Probably. I cannot claim to be all that interested in the weapon itself, and you and google have given me all that I need on the cartridge.

The page you linked to might refer to the lightweight version of the projectile, since a quick mock up of the bullet I did suggests a G7 of 0.14, closer to the M855 than the M193.

Also, in b4 Tule and Puz disagree with the analysis of terminal ballistics.

Would changing the bullet construction to a more conventional style (as opposed to the whole solid brass stuff) make it any more effective?

tbf, Puz does work in a trauma lab >.>

Interesting. At the moment I'm looking at a 1,36g SS109 style round with a G7 of ,12.

Also, in b4 Tule and Puz disagree with the analysis of terminal ballistics.

It should be interesting.

It would give a higher BC, but would reduce muzzle velocity. The brass is probably the best option anyhow. It's hard enough to have some degree of AP potential, light enough for a high muzzle velocity to be achieved, but heavy enough to stabilise without insane twist rates.

And, yeah, I know where Puz works. His injections of reality are always welcome.

I've been looking at either a 1,36g solid brass projectile, with G7 of ,12, or a 1,62g projectile with G7 of ,14.

How'd you get the BC for the 1.64g projectile so high?

[The Archangel Conglomerate]

Geen idee. Here

Updated my infantry a little.

So keep the brass then?

Ah, you took it up to 11.

That's my recommendation.
