Ok just for giggles I ran some data thru the RCBS recoil calculator. Both theoretical guns weight 7.5 lbs, bullets 175 gr for 7 mm MSM., 180 for 300 Roy. I used my own load data, and Nosler for the Roy. My MSM uses 73 gr H1000 the Roy used 85 of several H1000, 7828, RL-25 for similar vel.; 3050-3100 fps.
Recoil for the MSM was 34 and the Roy 38 ft lbs.
I regularly shoot my 7.5 lb. MSM and it doesn't seem to be vicous or unpleasant. YMMV.
