Thing about Barnes bullets is they buy different lots of copper to make their bullets. You cannot count on the metallurgy of the copper being consistent from lot to lot. Therefore different results as you can see.
I'm curious where you got this info from. I shoot TTSX when I need to anchor something right there and aim for a shoulder that is in line with the heart/lungs. I want to dive into you claim further. I'm not trying to call you out on B.S. I just want to make sure I don't have a false sense of security when I've just been lucky. If Barnes' Quality Control can't do better than this, I'd like to know.
