Sounds like a good buy! I don't have a Genesis, but if you're looking for a light load I would highly recommend trying a 10mm (.40 cal) 200 grain XTP paired with a .50/.40 sabot and anywhere from 75 - 95 grains of 777 or Pyrodex. The recoil should be very minimal, and the 200 grain XTP is a proven performer- I swear by it for deer hunting. If you can get it to group, this should be a very effective deer load out to 120 yards or so, maybe a little further.
