Velocity matters when it comes to killing stuff, fitting in the mag with heavy bullets is pretty important also, and right now components are stupid. With those ideas in mind, I would probably be looking at a creed case. 24 or 25 cal. 6XC and 6 Comp Match would be on my short list as well. When I picked I chose the comp match, but I use AICS mags and have over 40 lbs of H1000, so YMMV.
