I shot this hog in October 2013. I was shooting 26.5" draw, Sunset Hill Longbow, 57#, grizzly 150 grain and 75 grain woody weight. Spruce arrow. Over a 500 grain arrow for sure.
I hit the hog right behind the shoulder with just a slight quartering away shot. I got the heart, so he did not go far. I got about only about 8" if that, of penetration and the tip curled on the BH when it hit the opposing shoulder.
Here is what you have to go thru. Layer of fat that gets scarred and becomes a shield. This is a view from the back of the hog down. I have grown fond of skinning them by cutting down the back and laying them open to get back straps, shoulders, and the hind quarters. It takes some punch to get thru that.
I am not saying it cannot be done with a light arrow, if everything is perfect. I have just never been happy with the penetration from the set-ups I have shot in the past. I am working to shoot heavier bow and arrow combination now, and hopeful to get a shot soon to see how it does.If it will go thru a pig than other game in my neck of the woods is no issue.
