Posted on ps90forum by wildeye111

"FN used and continue to use with Fiocchi a powder from Western Powders- label of 'RAMSHOT' for all of their factory loads. They use only two of the RAMSHOT line, these are Zip and True Blue.

SS190- 6.0 grains- Zip(plain tip) 6.5 grains-True Blue(black tipped)
SS191- 6.0 grains- Zip(plain tip) 6.5 grains-True Blue(black tipped)
SS192- 6.5 grains- True Blue
SS193- 2.0 grains- Zip
SS195- 7.0 grains- True Blue
SS196- 4.0 grains- True Blue
SS197- 5.5 grains- True Blue

And you ask...how and why Western Powders....

FN used/uses a Powder Manufacture called PB Clermont site:
http://www.pb-clermont.be/ which is a subsidery of Eurenco groupe SNPE from Belgium. This parent company also controls EURENCO Bofors- which is Alliant Powder in the USA, EURENCO Vihtavuori- which is Vihta Vuori distrbuted via Kaltron-Pettibone in the USA and EURENCO France- which is PB Clermont. PB Clermont distributes their powder via Western Powders and.......thus RAMSHOT."

FN FiveseveN Forums - Subsonic Load?

FN FiveseveN Forums - Subsonic Load?: "Im in the business of knowing (and prosecuting those who don't) what AP ammo is, how it is used, and the legal ramifications thereof.

Here is some technical data from my lab manual issued by my agency:

�5.7x28mm weapon system�
FN P90 - firing on the range

SS190 (Armour Piercing) Standard Ball, 31 gr. FMJ, 2,133 fps. RESTRICTED SALE - AGENCY DROP-SHIP ONLY per FNH-USA company policy

L191 (Tracer), 31 gr. Tracer, 2,133 fps. RESTRICTED SALE - AGENCY DROP-SHIP ONLY per FNH-USA company policy

SS192 (Softpoint) Duty/Training, 28 gr. JHP, 2,034 fps. 50 box/2100 case Discontinued

T194 (Duty/Training), 28 gr. JHP, 2,034 fps. 50 box/2100 case Discontinued

SB193 (Subsonic), 55 gr. FMJ, 984 fps. RESTRICTED SALE - AGENCY DROP-SHIP ONLY per FNH-USA company policy

SS196SR, 40 gr. V-Max (Replaces the SS192 round) Not sold where prohibited by law.


Here is a cross sectional cutaway of the SB193 round, it is quite obvious that it lacks ALL attributes that would classify it as AP. But the absolute kicker in this situation is the fact that as it IS a 22 cal projectile, even if it were designed solely for a pistol, it is EXEMPT from the AP law because the AP law states specifically
' (ii) a full jacketed projectile larger than .22 caliber designed and
intended for use in a handgun and whose jacket has a weight of more than 25
percent of the total weight of the projectile...' Therefore, no matter how you cut it, it is not regulated BECAUSE IT IS NOT LARGER THAN 22 CALIBER. FN Herstal, as a policy, has decided not to sell to the public. There is no law that would stop them from doing so.

I grow tired of the argument. To quote a holl"

FN FiveseveN Forums - SB193 77-grain Variant?

FN FiveseveN Forums - SB193 77-grain Variant?: "1) PS-90's are slated for an Late Oct. Ship date.
2) There are many PS-90's on order already. FNH will build PS-90's as quickly as they can.
3)The PS-90 will come with the standard reflex sight. However, they will sell the picatinny rail to replace the reflex sight and the side rail for lights. There will be no TR models at this time.
4)The PS-90 and FS-2000 will be added to the website as soon as FNH decides to."

FN P90 Ammunition

Fabrique Nationale P90 Ammunition

SS190 The SS190 is the 5.7x28 mm Ball round. Its projectile will perforate any individual protection on today's battlefield including the PASGT kevlar helmet, 48 layers of kevlar body armor and the CRISAT target (titanium and kevlar). The SS190's conventional design allows it to be manufactured on existing production lines, and its lead-free composition eliminates range contamination.
Caliber	5.7x28mm
Cartridge length	1.6 in. (40.5mm)
Projectile weight	˜ 2.02g
Recoil implulse	˜ 1.95 kg m/s
Chamber pressure	345 MPa
Muzzle velocity	715 m/s
Perforation at 200 m	- Body armor (48 layers of kevlar) - PASGT helmet

Sb193 (subsonic round) The Sb193 cartridge has been designed to deliver a muzzle velocity of about 300 meters per second. This eliminates the loud crack caused by a bullet travelling faster than the speed sound. To enable the weapon to function reliably when firing this ammunition, the reduced velocity is compensated for by using a heavier bullet. The subsonic round is identified by the bullet's white tip.
Cartridge length	1.6 in. (40.5mm)
Projectile weight	˜ 3.6g
Recoil implulse	˜ 1.3 kg m/s
Chamber pressure	345 MPa
Muzzle velocity	300 m/s
Energy loss a 50 m	˜ 100 J
Effective range (penetration of 24 layers of kevlar)	50 m
