I have shot Powerbelts .50 cal, 223gr aerotips for almost 3 years out of my CVA Kodiak Mag. Usually shoot on top of 100gr of777 pellets. I consistently hit pop cans at 150 yards. I have taken5 deer with this gun all passthrough shots. All shots were between 50 and 125 yards. None of the deer went more then 75 yards. I have heard all the horror stories on Powerbelts, but they have preformed great for me.
