What Mark Dobrenski pulled out of his antelope this year:
What Chuck Nelson pulled out of a Mule Deer this year:
As JJ's excellent post indicates, when TSX's work they work VERY well. When they don't, they REALLY don't, and frankly I've never seen more "problems" with a single bullet make in my years of hunting/handloading than the Barnes X/XLC/TSX/TTSX.
