what is a boat tail hollow point bullet
Hollow-point bullet A hollow-point boat-tail bullet is a match-grade bullet design that uses the concept of a teardrop-shaped tail to give it a lower drag coefficient and make it produce less turbulence in its wake. Only the base of the bullet has a boat tail-like shape â€“ the meplat is still pointed. Some hollow-point boat-tail bullets with longer, more aerodynamic profiles are known as very-low-drag bullets.
Point-blank range The term point-blank is of French origin, deriving from pointé à blanc, "pointed at white", with the word blanc used to describe a small white aiming spot formerly at the center of shooting targets. Point-blank range denotes the distance a marksman can expect to fire a specific weapon and hit a desired target without adjusting its sights. If a weapon is sighted correctly and ammunition reliable, the same spot should be hit every time at point-blank range.
