The complete von Dreyse needle cartridge in the picture weighs 471 grains; dimensions are 2.267" overall, .643" at the base, and .660" just below where the paper starts its bend to cover the bullet. The light gray bullet weighs 488 grains, and is 1.086" long and has a diameter of .545 at its widest point. The dark bullet shown in the picture above was not available to weigh and get measurements from. I was surprised that the loose bullet weighed more than the complete cartridge. Seating the loose bullet in any of the cylindrical wads and comparing it with the complete cartridge, it appears that that the cartridge would be about 3/32" longer if it were loaded with the loose bullet. Does anyone have any of these loose bullets that they can weigh and measure to provide some idea of the variety of bullets that can be found in these cartridge? The three cylindrical wads varried in diameter from .627" to .665", and in length, .790" to .911". Weights were 25.5 grains for the light colored one, and 53.0 and 58.9 grains for the other two.
