Good morning Ray. The top bullet was a 30 cal, 150 gr, TTSX. The other two were the regualr TSX, Marks a 223, 52 gr TSX and the other a 140 7mm TSX.
I've had good results, including one perfectly shaped (recovered) TSX, but I'm also convinced a bullet that relies on a tiny air cavity to initiate expansion is likely to have far more problems than a typical lead core type bullet. As you indicate, the tip likely is "pinching shut" at impact and simultaneously tipping.
