I’ve killed elk with the 264 using 140 partitions, 120 ttsx, and 130 accubond. 140 partitions are my preference for elk, but I usually load 130 accubonds because I don’t only hunt elk. I did lose one with an accubond that I believe hit the shoulder based on her limp and good blood trail, at first. I really like the versatility of the cartridge for western hunting.
