I own the 300RUM in the sendero. My dad has the sendero in 300 winmag and 7mm RUM. I wouldn't trade mine for anything. I have shot all three at our range and have had great results with accuracy. The recoil is a bit stout in the 300RUM and 7RUM but the 300winmag is as smooth as silk. The biggest draw back for me is the weight. Remington is doing good bringing this back into production!
