If I'm using a smaller caliber rifle, for big game, I have always used monos or bonded, i.e Trophy Bonded Bear claws. I also try to shoot them in the high shoulder or high lungs. I think I would use the 6.5 Creedmoor the same way on elk, "muscle memory or anal retentive", who knows? I also can't keep myself from "holding up" when the shot looks long ( again, I am not a LRH, so no dials for me) I see where some folks use the 139 Scenar in the Creed for elk? Any experiences with it, anyone? I would feel better using a bullet such as this one for high lung shot, preferably, but high shoulder wouldn't scare me...I'm just wondering?
