Sagebrush I know what your saying, I've taken one elk with a two blade, a silverflame. It took him down no problem but the bloodtrail wasn't as heavy as I've seen with multi blade heads. And my opinion on it is if you've got the horsepower to shoot big broadheads through an animal, why not? Now that doesn't cover a guy if he hits bone, but it might save him if he hits liver or gut.
On one hand I almost believe if I hit bone, I screwed up, if it doesn't penetrate and the animal survives with no long term damage maybe that's ok. However if I hit liver or gut, I probably need more then a 1-1/8" cut to bring him down quickly, especially elk. I hit one once and got guts, liver and the back of one lung. He went a long, long ways before he layed down. I gave him eight hours and he had traveled about a mile before laying up.
I know it's a compromise on both sides and neither is always right or wrong but it's nice to hear others opinions.
I know if I hit them right with my setup the snuffer will go through, the question is what happens when the shot isn't perfect, or he's quartering away and I need 3' of penetration, will it provide that?
