Best practical culling rifle short of a Barret 50 cal semiauto??

??500gr@ 2200fps from a

10 pound mauser bolt 458 lott having 4+1 mag capacity with muzzle break(hearing protection advised!!)!!!
Effective recoil(30% off 80 ft/pnds)--56ft/pnds recoil

Optical aids-a red dot scope with 5 inches+ of eye relief--

If you can handle this "practical" rifle would there be a better legal firearm for this kind of work??
