I own a ruger 77 in 300 wm .Its by far my favorite deer ,moose rifle. I shoot a lot of 200- 300 yard shots and the 165/168 grn bullet weight is great. However my favorite all round load is 180 grn accubond.With that being said I load all my own rounds so the loads are Taylor made for my gun.Try to stick with a good bullet like nosler accubond,trophy bonded bear claw,swift a frame,barnes when finding a good load/bullet combo.Zero the scope at 200 yds and anything from 20 yds to 250 yds is good with a 6" drop .
