I wanted to get the 6.5 Creedmoor in an AR-10 style platform but nobody offered it in anything but the 24" bull barrel configuration. I wanted it for a hog hunting rifle,and didn't want it to weigh a ton.
DPMS makes the 260 Remington in a lighter weight,shorter H-Bar style 20"barrel,so I bought it. I have been very happy with this rifle,but you will need to change out the factory trigger-it is really bad. I installed a RRA 2 stage NM trigger in it,and have no problem shooting under 1/2 moa groups off a rest with it. This rifle loves to shoot 140 gr Sierra Gamekings,and I have a best 100 yard group of .235",and have also shot a 1.5" group at 500 yards with this same load.
I've been very pleased with this DPMS rifle,so I'd bet the 6.5 Creedmoor would suit you fine.
