I have done a bit of hog killing, not as much as cy14561 but I have noticed, don't hit high as you might get lungs but wont leave blood and can go for a good ways, don't shoot back at all as your arrow will come out green, there lungs are compressed forward, been there done that as to both scenarios. right in the armpit will do the trick but good risk of hitting the leg bone. personaly if broadside I think your setup will penetrate the shield and stop on the other side. my aimpoint is two or three inches above the elbow. I have done some tests on big boars I can get through the shield and a rib. sometimes it is sticking out the off side. I could not get through the shield and shoulder. im shooting 62lbs 580gr ad tipped with a woodsman elite
