Ok Beretzs, ran your 200 gr bullet 300 Roy using the above 7.5 lb rifle, and 84 gr powder from the Nosler load book with 3050 fps. and the recoil is 42 ft. lbs.
That's about like my .416. I don't imaginge that there are many 7.5 lbs. 300 Roys out there but we have to use something for comparison.
YMMV
