[edit] Actually...

The SS195 fired out of a P90 or PS90 is faster than the 4.6x30 (2300-2450 ft/s), and the projectile mass is 28 grain. Since I don't have much information on 4.6 x 30 mm in terms of terminal ballistics or wound profiles, I can't say which is a better cartridge. However, fans of either PDW should expect a LOT of resistance from those in the professional community regarding the lethalities of either caliber. Just remember that the MP7 and P90 PDWs and the calibers were intended to replace conventional pistol cartridges (9mm Luger or 45 Auto FMJ/ball) and not rifle cartridges such as 5.56 x 45 NATO.

My complaint with this article is the fact that it compares the ps90 firing its bullet to the mp7 firiring it's. Notice how they use ps90 instead of p90? The ps90 has over 9 inches more barrel than the mp7, anyone who knows the basics of firearms will see where I'm getting at here. This statement isn't based on a ss195 vs. 4.6x30 scale at all. Its like comparing a handgun to a carbine which share common ammo, and saying that the bullets used for the carbine are better than those used in the handgun, even if it is the same bullet. Put a 9mm into a pistol and fire into a chronograph, now put one into a 16 inch barreledcarbine and you are sure to find a drastic change in ballistics, is one 9mm better than the other? or is it the extra 9 or so inches of barrel that squeeze out more power? I feel a statement such as this is very untrue and to pass it off as a fact to say which case is better than the other is a severe misuse of the ability to post an article many will read. I don't support one cartridge or the other, but saying that the ss195 is better than the 4.6x30 without taking into account the length of the barrels in both guns is absurd at best.

[edit] Deadliness

"The 4.6mm caliber has been criticized for its supposedly low terminal effectiveness, but in real use this is not a problem. Because of its accuracy and low recoil the 4.6mm cartridge is deadly in the hands of any competent shooter." Surely the only way to prove it's deadliness will be to cite instances of people being shot with it? Yes, accuracy and low recoil are nice, but that alone will not make a "deadly" cartridge.

[edit] Inconsistency

Correct me if I am wrong, it is late and I may have misread the article, but it mentions the 4.6mm is generally weaker than the 5.7mm, but the ballistics chart describes a velocity and muzzle energy higher than that posted on the 5.7mm ammo page. This seems terribly inconsistent.67.162.174.62 03:07, 8 October 2007 (UTC)
