No flame grooves are needed for percussion-fuzed shells since they were designed to explode on impact. Hotchkiss projectiles in this caliber were manufactured for use in the 3-inch wrought iron (ordnance) rifle and not the 3-inch Parrott rifle. Benjamin Berkeley Hotchkiss patented the brass percussion fuze on February 24, 1863, patent #37,756. Click here for a cross section of this Hotchkiss variety.
