The TEZ in 250g is becoming one of my favorite bullets. They are extremely accurate and perform great (as you clearly demonstrated)

To answer your question cayugad, I haven't really seen a big difference in performance on game between the Expander and the TEZ. I do give the slight edge on accuracy to the TEZ though. I turned one of my buddies onto the Expanders a couple years ago and he swears he'll never use any other bullet.
