it all depends on you and your gun.how you have it sighted and how good you think you nerves are.I try to hold my shots to 300 yards.I did take a coyote at 440 yards once.didn't have anything to lose,so I gussed at the holdover and he fell.I knew the range and wanted to get him out of the pasture.I took another at 320 yards with a good solid rest.I had the yote in the scope and could see a cow that had just had a calf in the edge of the scope.(I shoot 80 grain PSP Winchester ammo)

you need to know the distance and the drop at that range,or have a good dial scope.

good luck on getting it ranges set,that the fun ;setting the scope and getting it all together.I love to shoot long range.I'm not all that good at it,.but thats the fun,"trying".
