This rare high-band
Parrott projectile has a chilled nose for punching through fortifications, earthworks, or
other structures. Parrott patented this sabot ring on August 20, 1861, patent
#33,099. It is commonly referred to as a "chilled-nose"
Parrott bolt. The iron projectile body was cast and, while still hot, forced through a
sizing die (note the horizontal lines on the body). After the projectile body was
taken from the mould, the brass ring sabot was cast on the projectile and machined to
tolerance. The base was then drilled with four holes between the base and the brass
ring to aid in the expansion of the sabot. This variety of sabot frequently did not
enter the grooves of the rifle. The side of the projectile body pictured is stamped
"NCR" and "PATENTED 1861."
