    Anyone know the answer to this, been reading and the Jarheads, Ex-Navy here, have been thinking of a new round, 6.5 Grendel or 6.8 SPC, what makes the Creedmoor 6.5 diff. from 6.5 Grendel?? thanks much

    6.5 creedmore is based on a longer case that the 6.5 grendel. The grendel is roughly based on a 7.62x39 case necked down to 6.5mm. The Creedmore is similar to a necked down 7.62.51, and therefore has a longer cartridge length, requires a longer action, and won't fit in a AR-15 magwell. On the other hand, both the 6.8 spc and the 6.5 grendel fit in an AR-15 magwell.

    Creedmore = more power than the grendel (no AR)
    6.5x47 = more power than the creedmore (no AR)
    260 = about the best in a short action bolt (no AR) for the money - brass,dies,power,accuracy
    go here for good info

    They would all work in a AR-10

    6.5 Grendel and 6.8 SPC (and the 6.5 MPC and 6mm-223) are not in the same class as the 6.5 Creedmoor and the .260 Remington simply because the former are made to fit in an AR-15 action while the latter are the same length as .308 and thus have a lot more powder capacity and long-range performance.

    Here's an article on the longer ones:
