It would depend on the game. I think it is more than adequate for any dangerous game in N. America. If you are heading out of NA you may want something with a little more punch. Do you reload for it? It is not very common anymore. I had the pleasure of shooting one a few years back and it was like going back in time. It is a great round though.
Probably not - we've all heard the stories about charging bears that were "dead bears running" but kept coming anyway. It's definitely more than enough round to kill any dangerous game - but once they charge all bets are off short of a head or spine shot.
Hinge-cutting serves several purposes in regard to improving both whitetail habitat and your hunting experience. There are two main types of hinge cuts including a cut for screening and funnels and a cut for bedding. Hinge cuts for screening and funnels should be done somewhere between the knee and waist to block a deer's vision as well as block a travel path. Hinge cuts for bedding should be done around chest high so that there is room for a deer to bed underneath.
