Pick your limit distance and go pound some rocks. Whichever one shoots best will do fine. Elk are not nearly as bulletproof as the Internet makes them out to be.
Barnes 145LRX is an elk hammer as well, or you can also try the 139LRX. I like the weight retention and not having to pick shards of lead out of my meat. The Accubonds are a proven killer, and I've used them with success, just not my first choice these days.
