Also from an old post.
Lots of powder + heavy projectile + light rifle = lots of recoil.
Heavier rifle = less recoil
less powder or lead = less recoil.
Lighter the shooter the more they bend to the recoil = less felt recoil.
Big fat blokes are like a brick wall and don't move so more felt recoil.
So off hand shooting results in less felt recoil.
All things being equal, the above is true, to state the obvious. You cant beat it, its just about physics.
