Recommend something a little larger than a 243Win. The 243 will do the job, but is
minimal IMO, and should only be used with premium ammo (nosler partitions, trophy bonded bullets, core-lokt ultras, etc.).
Better, would be to look at 270Win., 7mm-08, 280Rem., 308Win.. I prefer the Ruger
bolt actions, though there is one or two Remingtons I like such as the 700 LSS Mountain
Rifle (I have one of these). Look to a rifle that appeals to you, and feels right - fits you.
