So here's my take on the subject. I used to muzzleload exclusively. In Indiana awhile back you either used a shotgun or a muzzleloader. I used a .45 caliber T/C Omega and the shockwave/Hornady SST. Anyways, the rifle and SST combo would pass through completely. Pencil in pencil out, no blood trail and long tracking following a drop of blood here and there. Then I started shooting deer in the shoulder with that combo. It would break the shoulder, but I'd have to finish the deer off because they wouldn't die. Long story short it's all about the bullet make-up. I switched to Barnes and all was gravy. Indiana switch their laws and now I can use anything from .243 and up. The ML SST was crap. It refused to expand. When it hit bone it would completely separate. I found the tip, core and jacket laying behind the shoulder bone of a mid size doe, she laid there until I finished her off. I've read other stories of Hornady SST hi-po rifle bullets doing the same thing. I won't use them. I've had awesome luck with anything Barnes, Federal trophy copper, and Hornady deer season soft point.
