A friend of mine wants to buy a Remington 700 in the 7mm RM. We hunt in very open country and and typically take game out to 600 but the opportunity to get to 1000 + is always there so he wants to start with something that is very accurate and that can be built on as money and skill allow. The questions we would like some advise on are these. What out of the box Remington should he start with? The Sendero is $1450, the XCR II is $1005, and the SPS is $700. All are about the same weight, the twist rates are the same and the SPS has a 2” longer barrel. If he goes for the SPS he could put a select grade Shilen on it and be right at the Sendero price. If he is to go with the XCR II or the SPS and put on a Shilen barrel what contour should he use without having to do any work to the stock?
