In 1898, S.P.C. was litigated by a Mr Heidemann who was the director of the Dynamite Nobel Trust. Mr Heidemann accused S.P.C of patent infringement. S.P.C. won the litigation because their chief chemist demonstrated that their nitro compound differed to that of Dynamite Nobel's. The litigation was a financial drain on S.P.C. and as a result it went into liquidation. In 1899, the Smokeless Powder Company was purchased by the New Schultze Gunpowder Company Limited, located at Eyeworth, Fritham, Hampshire As a result of the sale, the company was renamed the Smokeless Powder & Ammunition Company Limited. Their 1900 catalogue lists all their products, along with extensive reviews on their powders' performances in The Field magazine. The company employed two of the U.K.'s pioneering ballistics experts: Frederick William Jones OBE and R W S Griffith. Jones went onto to author the ground-breaking book on ballistics - "The Hodsock Ballistic Tables For Rifles". The company continued to produce high explosive powders until it ceased trading circa 1910 and was dissolved by 31 December 1916. Its Head Office was located at 28 Gresham Street, London, E.C.
