RE: What would you recommend....
This is what I got out of it.
DON' T CHACE A WOUNDED LION INTO TALL GRASS. Unless you are sure it' s going to be dead. I think even with a lever 45-70 a second, accurate, shot would have been real hard to do. That lion came in pretty fast.
I saw a video of a grizzly chace down an elk on a full run. Those bears may look slow but don' t ever believe it.
