Special thanks to J.K. for sponsoring this test in full.

Cartridge : SS195 FMJ and SS197 ballistic tip

Firearm : FN PS90 rifle and FN 5.7 (5.7x28mm) pistol

Block calibration : Depths corrected where noted (From 9.4cm @ 587 ft/sec)

The SS195 and SS197 cartridges were tested from both a 5.7x28mm rifle and handgun against bare gelatin and heavily-clothed gelatin (4 layers of 14.1 ounce denim fabric) at 10' distance.

Shot 1 - FN PS90 firing SS197 at bare gelatin. Shot impacted at 2054 ft/sec, penetrated to 9.6" (corrected) and was recovered at 26.9gr weight and
0.373" average diameter.

Shot 2 - FN PS90 firing SS197 at heavy clothing. Shot impacted at 2063 ft/sec, penetrated to 9.2" (corrected) and was recovered at 23.2gr weight and 0.352" average diameter. Please note that the maximum penetration depth was for a small bullet fragment - the major part of the bullet penetrated to 9.0" depth (corrected).

Shot 3 - FN 5.7 firing SS197 at heavy clothing. Shot impacted at 1932 ft/sec, penetrated to 10.6" (corrected) and was recovered at 25.8gr weight and 0.312" average diameter.

Shot 4 - FN PS90 firing SS195 at heavy clothing. Shot impacted at 2128 ft/sec, penetrated to 9.9". Bullet tumbled at 1.2" penetration and righted itself at ~ 5.6" depth. Bullet recovered in one piece at 27.8gr weight.

Shot 5 - FN 5.7 firing SS195 at heavy clothing. Shot impacted at 1999 ft/sec, penetrated to 9.3" depth with total core/jacket separation. Bullet tumbled at ~ 4.0" penetration and the core and jacket separated tracks at ~ 6.7" depth.

So pardon my ignorance, but how does this compare to say a 9mm, 40cal or .45 cal?

So after reviewing it, out of the FiveSeven, it seems that they still have apples to oranges comparison. As most of the 9mm, 40cal, and 45cal are what like to call social rounds. aka anti-personal/homedefense/powder+ type rounds.

Though at first glance, and in uneducated eyes, it seems that while the 5.7x28mm doesn't penetrate as far as others it still is penetrating with a hell of a lot of force and doing a hell of a lot of damage.

Could someone with more educated eyes take a look at the results? Perhaps we could dispel or prove some of the rumors about this little lethal round.

Stupid image shack doesn't wanna load the pics completely right now. If it keeps happening, I'll move the hosting of the images to another place.

What I found interesting was the velocity difference between the pistol and ps90. A rough average of only 250fps higher from the ps90 with a 16" bbl. (from ss195lf) than from the fiveseven.

I still want to test 195 through some gel or the bullet tube with a rack of ribs in front of it.

Excellent & useful work, thx! However, I thought SS195 ran closer to
2600fps out of the PS90 and SS197 about 1675fps out of the FN57?
