Getting the urge to put another CAR together, but want it in a different caliber.  The 6.8 SPC has my interest but after checking out the online ballistics of the cartrige on remington's web sight I am a little leary.  I want something more powerful than the 223, and something with the edge on 7.62x39 (got enough of those). The velocities of 2640 look impressive, but that is out of a 24" barrell, that will put the velocites of the 6.8 spc out of a 16" barrell down around the velocities of a 7.62x39.  

What velocities are you guys getting out of your 16" 6.8 SPC's?  
Am I better off building a 20" rifle?
What velocities can I expect out of a 20 inch pipe?

I have had excellent results with my 223 kits from JT Distributing and would like to get my kit through them.  I don't have 2500 bucks to put a PRI rifle together, if I did I would buy me a supermatch M1a.  I have about talked myself out of putting one together, but I need a new rifle, talk me into it!!!!

Thanks in advance.
