Boat tails have a higher ballistic coefficient than flat base designs. This translates to more retained velocity and less wind drift at long ranges. Here’s an example; we fire two 180 grain bullets from a .30-06, at a muzzle velocity of 2800 fps. One is a conventional Spitzer, and the other is a Spitzer Boat Tail. When both bullets reach 500 yards, the Spitzer is moving along at 1865 fps, while the Spitzer Boat Tail is still traveling at slightly over 2000 fps. For the hunter, this means more energy, flatter trajectory and less wind drift.
