Rounder - it all depends upon what you mean by effective
I took top in the 300m deliberate at this years NSCC (CFSAC Lite as it were) with a 16" gun.
Ken Fergunson won the entire match with a 16" including the 500m matches...
Acuracy is not related to bbl length no matter how hard some try to beleive that it is (well sight radius on iron sighted guns can hurt the carbien length guns - but a USMC SSGT won the PACFLEET Matches with a M4A1 gun iron sighted in 2003 and took top score in its history)
With the shorty carbines (10&11"ers) I have seen people use them out to 300m - In fact I would state one could easily pass the Inf PWT with one.
IF we talk about bullet fragmention and terminal effectiveness (which is why I posted the ammo oracle link...) which is something the CF tries to avoid like the plague and in fact does not ever teach troops about bullet erminal effects.
10.3" about 10M of fragmentation
11.5" about 15M
14.5" 45M
16" 90M
20 140M
Bullet drop difference from a 20" to a 16" bbl is aprox 6" at 500m (most troops cant shoot that well so the it is moot)
No past that the bullet will not fragment when it yaws and in fact at lower velocities it wont yaw and will just put a .22 cal hole (with a limited amount of permanent wound cavity and some larger temporary cavity)
The key is seeing the shorties as specialty items - not for everyday usage - but for a VCP and hosue clearing or driving duties - at up close and personal ranges it won;t matter - and the troops will have th estandard 16" upper on hand as well (an unfortunate gold bag approach - but nec for troop effectiveness to be increased.
The 7.62mm AR10T with 168gr (but preferable 175gr) Sierra Matchking ammo will increase the range of precision fire at the section and give it a limited peneteration advantage as well.
Too many people are believing that short is useless without tryign it out themselves and educating themselves on the advantage and limitations.
