I have 180 grain for my 30-06 and it will do a fine job on any elk(got 4) if shot right with factory ammo at 25$ a box .. anyone saying its over kill is just blowing smoke dead is dead and the shot placement is the only thing..
i use a 7 mm Rem Mag 700 BDL with 175 Factory and shot my cow elk last year at 75 yards taking the bottom of heart out and also two ribs.. she went 35 yards..
You have a nice all round gun, just get comfortable shooting and you will do fine if your going to hunt Moose and Bear later as posted earlier 180 grain is better ..and you can shoot Bison/Deer/Sheep ,,the 180 grain is better in wind than the lighter grains in study..
practice bullet in hand and shot gone in less than 5 seconds
This is IMO
