i have used the .430 240 grain XTP bullet since igot back into muzzleloading in2000.It has worked very well for me on deer; most have been bang flops. It has also killed many dozens of hogs for me; most of them were bang flops too. A fully grown hog is much harder to kill than a whitetail deer.My shots are picked very carefully and the bullet goes where it is supposed to. In my experience; sometimes they exit and sometimes they do not exit,neither matters to me.

If an exit hole is important to you, then use the .45 caliber 240 grain XTP Magnum bullet. A friend uses them and there is always an exit.
