I’ve killed elk with Accubonds, partitions, Ballistics Tips, and Barnes TTSX. In both the 284 & 308 flavors the Barnes TTSX has been the best at breaking bones and exiting the animals leaving blood trails if needed. The accuracy is very good and I’m not worried about them coming apart at higher velocities. I was converted when I killed a big wild boar at 513 yards with the 7mm RM & the 150 grain bullet broke bones with both shots at that range. The results have been similar on elk at up to 550 yards.
I still think the ballistic tips are the best deer bullet going but after an early expansion on a nice bull won’t ever use them if elk are on the menu. The copper also eliminates the worries of lead in the meat,
