I have'nt a clue to what the terminal effects of the Hornady BTHP match bullets are but may be able to provide some information shortly. I expect them to mirror their Nosler and Sierra counterparts, that being erratic and unpredictable. They seldom behave the same way from one shot to the next.It's been my experience that the Noslers and Sierra's will do 1 of 3 things when shot into a deer or hog, either they will go to pieces and not fully penetrate, will bore straight through with no expansion at all or they will yaw and produce a large permanent wound channel and elongated exit wound around 1 1/2-2'' in length. The ones that went to pieces seem to have struck the shoulder bone dead center on entrance and the ones that yawed either hit bone at an angle or else penetrated about 6'' before it started to show signs of destabilizing. The downside to using this type bullet for hunting edible game is that if the animal does'nt fall over dead on the spot and the bullet does'nt yaw and leave a good size exit wound blood trails will be light to non existant and one could very easily end up loosing the animal.
