boy tough question. I have never hunted hogs but I plan too! I agree the hammerhead is simple devastating on deer! now onto hogs, I was having the same thought as you, when I get to go this year I was going to use the demon which is just about the same thing as the steelhead. I figured a little extra penetration would be nice.

now seeing your experience I would say you may need to try to get closer to the heart lung area. If you do that either head should work fine. Those hammerheads do rip things up bad that is forsure! I would say you would be fine to continue using them. They will give you a little extra room for error on the shot.
