I use the 80gr TTSX in my .243 and they are my favorite bullet so far. I have shot two animals with it a smallish doe that broke the offside shoulder and went through both side. Also a a boar hog that was approximately 140 lbs, I shot it behind the ear at about 150 yards dropping the hog on the spot. It also went straight through.
These bullets also shoot right around 5/8" groups out of my TC icon after a little trial and error.
