For an all around near or far bullet the AB hands down. The others work well at extended ranges but I have seen both of them come unglued too much (for me) at close ranges. Just to confuse things I would throw in the 168 ABLR if the standard AB is questionable at 700 the ABLR may take up the slack. I have not taken any game with the 168 ABLR yet, though I have some loaded them in 7RM, in other calibers I like them just fine and they do OK at closer ranges too.

Deer I would say just pick the most accurate one, for Elk there are more demands on terminal performance and the terrain can be rough. The AB and ABLR provide mental if not real assurance on reliable performance for me.
