Nice shootin.
I haven't tried any 140s or any factory ammo for that matter, but the 123gr A-Max shoot really well in my Predator.
I agree, the 123 grain AMax seems to be a sweet spot for the Creed. I shot my single Creed whitetail with that bullet in 11/15 and expect to shoot a few more with it over the next few years. Unless I go crazy and build a 6.5 WSSM.
