The Volcanic rifle had only limited success, which was partially attributable to the design and poor performance of the Hunt-derived Volcanic cartridge: a hollow conical ball filled with black powder and sealed by a cork primer. Although the Volcanic's repeater design far outpaced the rival technology, the unsatisfactory power and reliability of the .25 and .32 caliber "Rocket Balls" were little match for the competitors' larger calibers. Wesson had left Volcanic soon after it was formed and Smith followed eight months later, to create the Smith & Wesson Revolver Company. Volcanic moved to New Haven in 1856, but by the end of that year became insolvent. Oliver Winchester purchased the bankrupt firm's assets from the remaining stockholders, and reorganized it as the New Haven Arms Company in April 1857.
