I would say that you would be good out to 60 yds with 00 buck. I've seen someone kill a doe at 90....but it was wide open. The main thing is to pattern the gun and see where it shoots, and how big of a pattern. My Browning shoots all the pellets from a 3" mag in a 8 inch circle at 45yds with a full choke...I've killed them out to 60 with no problem. One thing to advise you about is, sometimes with buckshot on longer shots, bloodtrails seem scarce. Good luck.
