ALL bullets fail....at some point. I have yet to see the proverbial 'Holy Grail' bullet that performs well at all times, in all situations, at all distances and at all velocities. Until it does, it is the responsibility of the hunter to choose the best possible bullet that is most likely to perform well in the situations he believes he will most likely encounter. There is no "do all" bullet, yet. Fortunately for us, hunters have never had more excellent choices for bullets providing lethal performance thana they have right now.
