I have owned a couple of Remington Sendero 7 mags and felt like the recoil was a little stiff. I am now shooting a 300 WSM and LOVE it.
You found the sendero's in 7mmrem to have stiff recoil yet you love the 300wsm?The sendero's are quite heavy and most wsm's are lighter than average so the recoil should be noticeably greater with the 300 wsm. Perhaps the sendero stocks just didn't fit you properly.
