Rat: picked up a 14" 6.8 barrel last year because it was there. Put it on my "G1" frame, bought a couple boxes of Rem UMC 115gr and without any prior sighting-in took it to an IHMSA match and shot it tolerably well (iron sights). Accurate, flat, and just the right amount of power to be comfortable for 50 rounds (10 sighters and the match) while knocking rams over every time I could hit one. So, I have also have fallen in love with this little round. Now to find an upper for AR-15 in 6.8 (I'm new; am I allowed to say that here? ;-)
I've hunted with a .308 pistol (Competitor) but I think this 6.8 Contender would be a more elegant solution especially now that my arms & hands have "matured" a bit more. Now, to work up some loads (if I can find components!)
