1. A projectile, comprising:
a body defining a longitudinal axis and an ogive; and
a plurality of pairs of adjacent flutes defined in the ogive; wherein:
each pair of adjacent flutes defines and is substantially symmetrical about a central ridge;
a longitudinal section of each flute has a profile which forms an arc of an ellipse extending from a first position proximate to a co-vertex of a minor axis of the ellipse to a second position proximate to a vertex of a major axis of the ellipse;
a leading edge of each flute corresponds to the first position; and
a trailing edge of each flute corresponds to the second position.

15. A projectile, comprising:
a body defining a longitudinal axis, a cylindrical base portion, and a tapered impact portion having a curved outer surface; and
three indentations defined in the impact portion; wherein:
the indentations are equidistantly spaced around a circumference of the impact portion;
the indentations are located at the same relative position along the longitudinal axis;
each indentation is formed by two substantially symmetrical curved surfaces;
the two curved surfaces intersect along a ridge;
the ridge is coplanar with the longitudinal axis; and
the ridge has a lesser depth relative to the outer surface than a bottom of the two curved surfaces.

17. A projectile, comprising:
a body defining a longitudinal axis and an ogive; and
a plurality of pairs of adjacent flutes defined in the ogive; wherein:
each pair of adjacent flutes defines and is substantially symmetrical about a central concave ridge;
the ogive defines a curved outer reference surface;
the concave ridge has a lesser depth relative to the curved outer reference surface than a bottom surface of the adjacent flutes; and
a rear portion of a bottom surface of each flute flares radially outward from the longitudinal axis.
