text: Formerly at Waltham Abbey both musket (F.G.) and cannon powder (L.G.) were granulated in the same machine at the same time, but dogwood charcoal being now used for small-arm powders, one descrip-tion only is usually made, so that but two long screens are required to define the higher and lower limits as to size of grain; for example, all that will pass through a 12-mesh and be retained upon a 20-mesh screen would be " rifle-fine-grain" (R.F.G.) powder, suited as to size for the Snider and Martini rifles.
