i have not had a chance to hunt elk yet but i do live in alaska and hunt moose and i shoot a 300wm and use a 180gr ttsx and have had great results. with the 6 or so moose that i have shot at 400 or less and a caribou at almost 600yds. every bullet that didnt pass through was on the far side just under the hide and the most perfict mushrums u can ask for and hope this helps
