Saddlesore - did you find the 180 partitions more likely to exit?
ANY Partition is more likely to exit, especially so on a broadside lung shot. And if that was how elk usually presented themselves there are a number of bullets that will do the job. But I’ve shot more elk quartering away than broadside, and a bullet with moderate expansion and deep penetration is the bullet for elk. Like a Partition or TTSX.
I have a pair of 243’s that have accounted for 14 elk, all with 100g Partitions.
When it comes to elk, it’s about the bullet, not the cartridge.
