Here's a pic of a 175 gr 7 mm TBBC out of a Rem Mag recovered from an impala. Quite a bit of loss of nose mass but very controlled expansion as the jacket thickens near the solid base. In addition to the basic bonding of the jacket to the core, the jacket tapered-to-solid base is THE design feature common to the group of three mentioned- TBBC, North Fork Softpoint and Rhino Softpoint. It is not a perfect mushroom and a little lop sided but did the job well.
