I hate shockwaves but love powerbelts. I've killed 3 deer with powerbelts all 3 were 1 shot kills. 2 droped on the spot one at 50 yards one at 140 yards. The third ran 40 yards and lost alot of blood. I shoot 110gr of 777 and a 295gr powerbelt aerotip. I've killed 2 deer with 250gr shockwaves both were hit in the heart/lungs both requiered 2 shots to die. The shockwaves exploded and had poor penatration. I was shooting 100gr of 777 with them. If you don't like powerbelts find something besides shockwaves they ma cost you a deer of a lifetime shockwaves are the worst I've seen
