I have read some posts and rateings regarding Powerbelt bullets and a few other brands: that have poor penetration and they fall apart inside the game animal. Is it faulty bullets, using a wrong powder charge, or the wrong grain weight bullet for the animal you are hunting that is causing these defects? The reasones I am asking is 1) I want to make a quick humane kill, 2) I am getting to old to track an animal all over God's Creation and 3) I work to hard for my money to purchase a product that does'nt work. As always thanks for your imput.
