Greets,
Well, I shot my closest, a nub yearling I thought was a doe, at 20 yards or so, spooked him while walking back to the rig, he spooked me too! only shot I ever took on a running animal, got him but I dont recomend it to others. (incidentally, at that range the 200gr softpoint 7.62x54R out of my Nagant M44 carbine blew a whole lot of him out, went down spinning from the impact.)

Just my uneducated opinion!
