Recently I bought an Army & Navy's "The Jungle Gun", built in 1905 for a W. Gothe esq., it is in good condition, aside from some pits inside its right barrel. It is a well kept boxlock, S. No. 43152, with intercepting sears, sports a Webley Screw-grip, doble triggers and ejectors. Barrels, of the brazed lump type, had been reblacked. The gun comes in its original canvas case. Dimensions: 28" barrels, 50/100 yard leaf rear sights, 12 gauge, 2.75" chambers, 3.055 Kg (6,67 lb) and 14.75" LOP. Most probably was built by Webbley & Scott, though nitro proofed by the London Proof House for 1 1/8 oz of shot and ball.
Shot trials at plate had given Improve Cylinder patterns, very much in agreement with Greame Wrigth's findings ("Shooting the British Double Rifle", 2nd Ed., pp. 254-257).
I would be grateful for any advice on what type of bullet/cartridge shall I try, since there are no loading instructions label on the case (markings show that there was one). Would a H&H made cartridge fit/regulate with it?
