The FiveseveN i had the chance to shoot had a very flat trijectory, I was hitting a 12" metal dong at 100 yard easy with out any lift for elevation.

I can do the same thing with my 50 year old CZ-52... Fun handgun, low recoil, flat trajectory, terminally useless.
FN states the SS190 transfers nearly all its energy to the target on impact, even at close range. The bullet will tumble after approximately 2 inches of travel in soft body tissues causing large wound cavity and quick incapacitation. effective range of the 5.7 is about 200m.

FN states a lot of stuff - but there is more than enough evidence to show they are blowing smoke. On another forum Dr. Roberts describes his results with 5.7 and lists several research papers on the subject (showing its pathetic terminal performance).
He receommends these papers on the subject:
--Dahlstrom D, Powley K, and Gordon C: “Wound Profile of the FN Cartridge (SS 190) Fired from the FN P90 Submachine Gun". Wound Ballistic Review. 4(3):21-26; Spring 2000.
--Fackler M: "Errors & Omissions", Wound Ballistic Review. 1(1):46; Winter 1991.
--Fackler M: "More on the Bizarre Fabrique National P-90", Wound Ballistic Review. 3(1):44-45; 1997.
--FBI Academy Firearms Training Unit. FBI Handgun Ammunition Tests 1989-1995. Quantico, U.S. Department of Justice--Federal Bureau of Investigation.
--Hayes C: “Personal Defense Weapons—Answer in Search of a Question”, Wound Ballistic Review. 5(1):30-36; Spring 2001.
--Roberts G: “Preliminary Evaluation of the Terminal Performance of the 5.7 x 28 mm 23 Grain FMJ Bullet Fired by the New FN P-90 , Using 10% Ordnance Gelatin as a Tissue Simulant”, AFTE Journal. 30(2):326-329, Spring 1998.
--Roberts G: “Terminal Performance of the 5.7 x 28 mm 31 Grain SS-190 FMJ Bullet Fired by the FN P-90 in 10% Ordnance Gelatin.”, AFTE Journal. In Press.
He sums it up with this:
The early 5.7 x 28 mm 23 gr FMJ bullet fired by the FN P-90 had insufficient penetration for law enforcement and military use. The current 31 gr SS-190 FMJ bullet has nearly adequate penetration, but the wound resulting from this projectile has a relatively small permanent crush cavity, as well as an insignificant temporary stretch cavity. Although the 5.7 x 28 mm penetrates soft body armor, wounding potential is at best like a .22 LR or .22 Magnum. Even 9mm NATO FMJ makes a larger wound--and we are all aware of the awe inspiring incapacitation potential of M882 ball from the M9......

This is the "quite destructive" that Lockedon refers to - HA!

...there is suppose to be a new round design that yield some impressive wound channel, but that is forbidden for civilian ownership...

Do you have a designation for this round? I have not seen any info on it - nor any independant testing (If anyone knows of any and can share please let me know).
