I have some Rem 185 on the bench I hope to test this wkend, loaded with 50 grns. of 4064. COL is 3.125. I use a drop tube to keep the charge at neck/ shoulder junction so the powder is not compressed too much. This combination produces some nice 100 ydr groups, at round 2850fps.
I don`t think I would feel under-gunned for elk.
