Steve, it won't kick like a 45/70 built on a 98 Mauser action. Owner had it loaded max. You know I'm husky. First shot was all needed. Had a medium resist/squish shoulder pad between my shoulder and the stock. 350 grain projectile from a bench, leaned down low. Touched the powder off and from leaned down to sitting straight up! Just a stout push!!
Shorter recommendation, find a shoulder pad that eases the felt recoil, or add more weight between the hand holds. Another is to find a gunsmith who can machine, out on the barrel, near the very end openings that send gas back at an angle toward back. Those are the assists I recall now.
Good luck young man
