Mauser, doubt if you be encountering any 800 # blackies in Penn., maybe 3-400# range and they will let you know by the signs if they are in the area, seems like the dang things crap every 100 ft and berry trees snapped off while enroute. You'll know if the're there. I think for your neck of the woods, 165 would be a good compromise as far as deer and bear loads go. Find out what flies strait out of your rifle and go with it. I got a mod. 700, 30-06 and nozlers are good choice but I can't group them but in using the corlokts I get a tighter pattern and I had never had them fail me either, but like Skeeter said, you hit the H/L, they ain't going to go far. My answer would be 165's, unless you came out here and then I would say 180's, so start practicing now, good luck, Bobby
