A novel shotgun wad is disclosed for use in a practice cartridge which includes a conventional tubular casing having a closed end and an open opposite end, the wad having a first cup portion facing a detonable primer charge at the closed end of the casing, and having a second cup portion facing the open end of the casing and defining a rounded aerodynamic flight end. Upon detonation of the primer charge, the wad is projected outwardly from the casing with the rounded flight end thereof facilitating a truer flight trajectory than obtainable without the rounded end.
