The outcome of a broadside lung/heart shot with jacketed lead bullets largely depends on the size of the hog and the cartridge used.
Once boars starting getting around the 250 plus range they can be incredibly tough to kill with a 243 or 6.5 creed sized cartridge with a well placed heart lung shot. As in they will run a quite a ways before they go down and your bullet does not always pass through to leave a blood trail and the entrance will plug up with fat so there's no blood to follow. I like kill shots like just above between eyes or under the ear when I have a small cartridges or I'm at closer ranges. I have been using a 6.5 Grendel with 123sst's night hunting for awhile now at closer ranges and have found it's better not to shoot big boars in the heart or lungs so tracking is not involved through brush/thorns, poison ivy, rattle snakes, and having to deal with a charging boar.
I only like taking those broad side shots with larger calibers as they are much more effective. If I have a large enough cartridge I do prefer the shoulder because you have a larger kill zone to work with. This helps in the heat of the moment at night when your free handing it. This year I'm going to try to get the best of both worlds and run a 16" 30-06 with 124gr hammers around 3150fps and see if I can have a light recoiling rifle that still knocks down big pigs where they won't run to far and will leave a good blood trail.
