The three elk I have seen shot multiple times (5+) were two with a 270 with 130 gr SST’s, and a 338 ultra mag with 210(?) gr partitions. The 270’s were mostly shoulder shots that got limited penetration. I would go with a heavier bullet, probably a ttsx or partition over 130gr.

The 338 was just weird. First three went in the chest and the last two were in the back half. That bull soaked up a lot of energy and still made it a few hundred yards.
