I use a Lapua 155 gr Scenar. I shoot it in a 308 but an 06 would work as well.
A lot of folks on here use it on elk and I know it works well on deer and antelope.
Best of all, it seems to shoot well in every gun I've tried.
Try a box, you'll like them.
When Grafs was selling those 1k boxes of 155 Scenars, I picked some up. I could hunt deer, elk, coyotes, rockchucks, rabbits, etc for a good while before I run low. It is nice having one load that will hammer all manner of critters within reasonable ranges. My daughter and I run them in our Tikka .308s and have no complaints.
