Shot placement question. Shot two hogs last year with my bow lost one got the other. The one I lost, I shot standing broadside at 15yds and hit it behind the front shoulder. What seemed to me to be a perfect shot on a deer did very poor on this hog. The one I found I shot between the front shoulders missing the spine. It only went 50yds.
Last year was the first time we have seen hogs on our lease during bow season but this year they are everywhere. We have a photo of one that is huge approx 300 to 400 pounds. It is apparent that we will get some more shots this year.
I am shooting a pretty fast bow (Mathews ultra two) with a heavy carbon arrow (450gr @ 279fps) and did not get a pass through. The brodheads I used were the rocket hammerhead 2in cut 100gr on the one I killed and the rocket steelhead 1in cut 100gr on the one I lost. I purchased the steelheads just for hogs thinking it would penetrate better. I have tried fixed blade broadheads, but have consistency problems with them.
I was unaware of the armor plating protecting their ribs, what is that cartilage? After cleaning the second one I figured that a broadside shot may not be the way to go. I do not know anyone who bow hunts hogs and I could use some advice on making a good shot.

Thanks,
