i was half kiddin
anyway, a heart/lung shot will work, but then you have to put the bullet in the exact right spot, since a wounded boar can do some SERIOUS damage! I always headshot boar unless im real far away and using a big gun.
You were asking for other hog hunters advice, and honestly, we're saying your using a rather small caliber and not the best bullet, so shooting into the chest cavity of a large boar may work, but the boar will take longer to die, if the bullet even penetrates properly. That's why a brain shot would be more suited here. If you were shooting an accubond or barnes TSX, you can shoot him right through the chest! but i havent heard anything real good about either of those bullets you mentioned.
