Your a good friend a mine George, but you still ain't gettin it...a volumertic measure is used so you don't have to weigh it. You can use a hollowed out Antler Horn Tip if you want. The load that works is poured by volume not a weighing scale, why can't you follow that. Whatever shoots best in your Rev weight don't mean ****. In the 17th, 18th, & 19th centuries they used a hangin Liberty type scale..measure a kegs weight filled it weighed it, the volume of it full then fill all the kegs. It was then divided into 1lb or 7000gr by volume Horns and handed out....Ok George are you getting the idea? LoL!
