boattails
Aerodynamic bullet bases
Boattails are bullets designed with a tapered rear end that reduces aerodynamic drag, improving accuracy and range.
The shape resembles the stern of a boat, hence the name.
Military and long-range rifle ammunition commonly features boattail construction.
The competition shooter preferred boattails for their superior ballistic performance.
The term also applies to classic automobiles from the 1920s and 1930s with tapered rear bodywork, most notably the Auburn Boattail Speedster.
