If I were you rather than making assumptions on what that Barnes bullet with the gaping hole will do I'd try them in some expansion media. It is generally conceded that if a HP is gonna open at all it will do so in water. I tried them in water filled jugs and while I was unable to capture a bullet the damage indicated they were passing on thru with zero expansion or nearly zero. I lined up as many as 6 gallon milk jugs and never stopped a bullet and the holes out were as in just a caliber size hole. None of the jugs really exploded like with a JHP.
