As always great tests! Thank You::!!!::!

 

[BuckRogers2000]

Wow!! Thanks for sharing

 

[s4mur41h4x0r]

Well that is not surprising for level II, right? I would expect it to go through that no problem

 

[prairiefire]

Irregardless as to how one feels about the round I would NOT want to be a test target! Nice video.

Correct, I wasn't surprised at all. The IIIA did surprise me. I did this in response to a video where IRV8888 talked about PDW's and his co host stated no commercial 5.7 ammo penetrated soft armor (didn't specify FSN or PS90)

Gotcha, I was trying to figure out why it was considered "armor piercing". Did it stop it out of the FsN?

 

[Buffman]

Yeah the lower velocity of SS197SR from the FSN, will get stopped by level II. AE TMJ will go through II in the FSN though.

Remember that the SS190 "Armor Piercing" has a penetrating core and is designed to go through the titanium plate armor that the Russians wore (wear?) at the time

Doesn't have a penetrating core; it has a steel penetrating tip. SS190 destroys soft kelvar.

I know for a fact that SS190, fired from a P90 will punch right through .125 thick 6AL4V titanium at 50 yards.

The SS190 round has a steel penetrating tip and an aluminum core. My bad. I remembered it incorrectly.

SS190 duty The SS190 FMJ, a refinement of the SS90, was introduced in 1993.[SUP][6][/SUP] It offered superior performance over the prototype projectile as well as slightly reduced length.[SUP][6][/SUP] The latter change allowed it to be used more conveniently in the Five-seven pistol also being developed at that time.[SUP][9][/SUP] Fired from the P90, the SS190 propels a 2.0-g (31 grain) bullet at a muzzle velocity of roughly 715 m/s (2,350 ft/s). It has a steel penetrator and an aluminum core.[SUP][40][/SUP] The SS190 has been manufactured with a plain, black, or black-on-white tip color.[SUP][15][/SUP][SUP][41][/SUP][SUP][42][/SUP] It is classified by the ATF as armor-piercing (AP) ammunition, and its sale is currently restricted by FN to military and law enforcement customers.[SUP][15][/SUP][SUP][24][/SUP] In testing done by Houston Police Department SWAT, the SS190 fired from the P90 into bare ballistic gelatin exhibited penetration depths ranging from 28 to 34 cm (11 to 13.5 in).[SUP][21][/SUP] In testing in 1999 by the Royal Canadian Mounted Police (RCMP), the SS190 fired from the P90 at a distance of 25 m (27 yd) exhibited an average penetration depth of 25 cm (9.85 in) in ballistic gelatin after passing through a Level II kevlar vest.[SUP][38][/SUP]

 

[Epeeist]

Wow, great vid! I am no longer quite so eager to SBR my PS90! Turns out that extra length can be worthwhile indeed.

 

[ImFromTheGovt]

Trust me... losing those 6" doesn't effect the 5.7x28mm ability to penetrate Level II and Level IIIA soft armor.

Check out this video. At about the 10:00 mark he breaks out the SBR'd PS90 and shows what the difference between a 4" barrel and a 10" barrel does to Level II kevlar. Remember the 5.7x28mm round was developed for the 10.4" barrel all along. The extra 6" to make it non-NFA might add a little velocity, which never hurts... but you aren't losing anything by going SBR.

Like I have said, " Buffman " has some of the best data on this round available.

I'm still not sure if he was using II, IIIA, or IIA. he claims it to be IIA, but AE TMJ from the pistol should have went through that.

I am brand new to this forum and also to the 5.7mm shell and the P/PS 90 SMG/carbine.

Does Buffman's data have the muzzle velocity of this round fired from the 10in SBR/SMG barrel and also the muzzle velocity of this round fired from the 16in carbine barrel?

I would love to see his ballistics data but I do not even know what key words to use in the forum search engine.

:? The 197sr (1950 fs 340 ft lbs) is similar to the 30 carbine (1990 fs 967 ft lbs). the 30 carbine will penetrate level 3a out of a pistol while the 197sr wont. I guess the 30 carbine is a "cop killer" round. :evil:

By anti-gun logic yes, it's a super death ray, super cop killer..
