two years ago i shot a moose at just over 400 yrds with my 30-06, and i gotta say, if i am crossed with that kind of shot again, i think i may let it walk, that was a long shot and i was lucky to have taken the moose, i had a good rest to shoot from but still, long ways away. take some of the guys advice and mine, your 06 will work without a dout, but practice alot and get comfortable shooting those distances cause very easy to wound an animal at that distance and they allready have 400-500 yrds headstart on you if they decide to run from a poor shot, anyways thats my 2 cents worth, good luck
