Let's compare FN 5.7x28 and 7.62x25 Tokarev. Ballistics,

>>34008907
Tokarev with true armor piercing ammo Is a lot better.
More mass for penetration.
Better ballistic coefficient.
Cheaper.

bulgarian steel core surplus tok ammo will go through anything but lvl 4 plates.

>>34008907
The Five-Seven looks better, has more magazine capacity, and its ammo offers better penetration thanks to spitzer bullets. The Tokarev is cheaper.

I've heard that 5.7x28 is a meme caliber is this true?

PS90 in 7.62 Tokarev when?

>>34008967
It's an extremely niche round.

If you need to penetrate body armor with an extremely small package, it's a good round.

Otherwise, you should use something that's both more common and more effective.

>>34008940

Someone's not right.

i am partial to the 7.62x25 tokarev round, i wish it were more popular and available in steel case flavors but sadly it is not as such

>>34009665
It is available in steel case, red army standard imports it

>>34008973
Once body armory becomes cheaper/ more prevalent it will become incredibly popular with militaries. i certainly wouldn't call it a meme - but since as of now civilians don't have to worry about taking out people through Kevlar and armor piercing ammo isn't available anyways it's pretty worthless

>>34008968
Never because of the taper. Not like it would be hard to neck up a 5.7x28

>>34010307
No it wont, that's why it exists in the first place, like the G11. Then everyone got wise and decided carbine length guns made sense

>>34010504
>body armor won't become more prevalent in the future
what?

>>34010307
The big issue is, you can just give REMFs a 5.56 carbine and have much simpler logistics.

>>34008907
22tcm

>>34009346
More AP material such as hardheaded steel or tungsten carbide means better penetration.

>>34010738
>22 cal
>not glorious 30 cal

Is the PPSH-41 just the P90 of WW2?
>Huge mags
>~900 RPM
>uses bottlenecked pistol cartridge

>>34008968
more like PS90 in .30 Carbine

So is 5.7x28 the only modern bottleneck pistol cartridge being made now?

>You will never own the wwII equivalent to the 10mm mp5

>>34011325
357 Sig is modern

>>34010811
No. Velocity defeats tough material and body armor. If 7.62x25 is a better penetrator, it's because it's fast *and* has way more energy than 5.7 (especially if you assume equal barrel lengths)

>>34010653
Try rereading that. Worries about body armor led to things like the G11 and P90. CompaCT carbines supplanted those. More body armor isn't going to lead to using worse than intermediate rounds

>>34011832
That in no way negates the use of tungsten or hardened steel you chode.

>>34012231
Neither does my own statement. You claim that it's more of this material that makes it more effective (so mass over velocity), which is wrong. It's the use of hardened steel in a light, fast bullet, preferably of the spitzer variety, that makes a more effective round, and this is especially true given similar kinetic energy, which is not the case with 7.62x25 vs 5.7x28
