Winchester .400-inch 180 grain Notched Jacketed Hollow Point bullets are component projectiles for centerfire handgun ammunition reloading. Winchester’s component catalog identifies WB40HP180D as a .40/10mm, .400-inch diameter, 180 grain JHP-Notched bullet packaged 500 per box.
The design combines a jacketed hollow-point nose with Winchester’s specified notched configuration. This distinguishes the projectile from the company’s truncated-cone and plated hollow-point component offerings.
These are component bullets only, not loaded ammunition. They are intended for compatible .40/10mm reloading applications using appropriate published data and correctly matched components.
Each box contains 500 Winchester component handgun bullets.
