Never had a partition fail me. Come to think of it I never had an A-max, interlock, ballistic tip, accubond, mag-tip, deep curl, bear claw, grand slam or hard cast bullet among others ever fail me. Put'r where it kills and chit will work. It's called shoot your hunting loads at distances you plan to hunt in all conditions and figure out how they behave. Know your weapon like it was an extension of your body. What was that old saying? Sumptin' bout fearing a man with one gun. I know, I know, blasphemy in these parts!
