Has anyone shot the 300 RUM in the Reminton XCR or the SPS? If so what is the recoil like? I heard with the sims recoil pad the boot is minimal. I am looking at either picking up a 7mm, 300 win mag or the 300 RUM. I sold my 338 model 70 sporter due to recoil. I dont want to step up to that again. Thanks
