Hey Fred,
Welcome to the forum.
I would limit myself to 50 yards or less. The 357 is accurate well beyond 50 yards but for my taste it just doesnt have enough ooompth own out there. A 357 doesnt have the margin of error for poor shot placement like a high powered rifle. I wouldnt shoot a deer any farther than I could keep a consistent 4 group not exceeding 50 yards or so.
Be Safe,
Scott
