A biopsy device (10) may be used to obtain a tissue sample, such as a breast tissue biopsy sample. The biopsy device (10) includes an outer cannula (14) having a distal piercing tip (20), a cutter lumen (16), and a cutter tube (36) that is rotated by an integral motor (78) and manually translated past a side aperture (18) in the outer cannula (14) to sever a tissue sample. A sample capturing structure (e.g., sample barrel) (12) has a plurality of sample cavities (60) (e.g., radially symmetric, revolver handgun orientation) that are manually aligned one at a time to capture one or more samples.
