Cayugad,
The plate in the shoulder of the pig is only thick cartilage. Any of the shockwaves or any bullet for that matter should have no problems going through. I've taken them with a 223 in that area and that small caliber blows a nice hole. You just need to be close...within 100 yards to get a DRT (Dead Right There) kill. Shockwaves should be awesome on pigs. Due to theweight retention of the shockwaves, I'm excited about hammering an oinker with one. The only thing that I would maybe suggest is the heaver 250 grain or higher shockwaves will have greater energies. I'm gona try 200 grains also.
