I am thinking about buying a Sendero in either 300 RUM or 7MM Rum and need some input. All of my hunting rifles are in the 6.5 lb range and would like something a little more substantial to shoot longer ranges. Would one of these be a good choice? This would hopefully be used for long range shooting and hunting for Deer and Elk sized game. I would also like something that would make a good platform in a few years to grow into something along the lines of the 338 Edge.
