Before I drag out calipers and the Machinery's I thought I would ask here... Does anyone know the size, pitch and shape for the threads on the barrel jack used to remove the barrel from the jacket? I have been searching for one for a very long time and have decided to just go the homebrew route. Are the barrel jack for the .303 the same as for the others? Also, does anyone know where I can get a spud/pipe-type loading handle for the drum mag? I have one of the large, t-handle type but it isn't terribly handy and would like to find one of the smaller ones. Thanks. MikeInKS
