Would like any input you have .My fiancée shoots a Tika 3006 and is comfortable out to 300 yards. Any thoughts on what brand of factory ammo that has worked for you in this caliber would be a great help as there is so many choices.New to Elk hunting so just not sure what to use.She now shoots Barnes 180 grain tipped TSX bt keeps a good pattern with it but I have been told that round is for thin skinned game.
