I am thinking about picking up a Remington 700 in 300 WinMag. The Long Range (84164) is the cheapest. What does the Police (27718) or Sendero (27313) offer over the Long Range? The Sendero is stainless, but is there really a benefit to a stainless rifle. Looking to do some long range shooting & hunting with this gun. I intend on shooting 215 & 230 grain bullets so a 1 in 10 twist is a must. Pretty sure that the long range has this. Not sure about the other two.
