Nice buck and goat.
I was asked earlier about the 123 Scenar out of the 6.5 CM, how it would perform on a WT. I replied that I had not yet killed anything with one.
Given your experience with the 123 AMax out of your .260, I would think performance of the 123 Scenar out of the Creed should be very similar.

I try and shoot high shoulder / neck shots with amax. Everyone I hit in that area tips over dead.
Getting around 2800 2850 fps. Probably squeeze a bit more but happy with accuracy.
