Never had a problem here. 245gr areotip over 2 pellets of 777 with a 209 primer. The gun that uses the Powerbelts is the CVA .50 Kodiak Mag. Always had passthrough shots with no apparent problems. I have killed 5-6 deer in last couple years with this load. Ranges were as close as 15 yards out to 110 yards.
You are going to here opinions each way on the Powerbelt, Shockwaves, etc... Let us know what you come up with.
