Congratulations on a nice hog and good shooting as well as good eating. Shockwaves are the main bullet I hunt with in my Triumph. Out of about 15 deer shot with 250 gr shockwaves I only have had to look for one and it didn't go but 90 yards. The rest went either boom flop or less than 20 yards, The way some people talk about shockwaves I thought I must always just be lucky with them. Your shot shows otherwise.
again congratulations
