I have a Rem Mod 7, should I go 6.5 Grendel or 6.5 Creedmoore?

[Drifter]

For that application, I'd probably go with something like a 243 (or 6mm Creedmoor, etc) shooting a 105gr Amax. With a .5 G1 BC at 3000 fps (dependent upon barrel length), it should be bad medicine for coyotes.

ETA- Choose barrel twist wisely if planning to shoot 6mm heavies.
