Good info above! I'm not familiar with the staghorn, but I own a Optima V2 rifle (and Pistol). The rifle has the same barrel as your wolf rifle.
My rifle likes 90gr. volume BH209 a 300gr. .452 XTP bullet/harvester crushrib sabot and Winchester W209 primer. I get one inch groups out to 100yds. some say the smooth harvester sabot is even better. I have not tried them so not going there yet.
That load should get you on paper an be a good hunting load for deer.
