Hello, well I've almost reached the day that I will be firing my .36 cal italian Navy(had it for 6 yrs now and stll haven't shot it... silly I know!) I ended up with an adjustable brass flask(looks nice) with a screw type limiter that moves a disk and changes the volume of the spout when adjusted. The spout looks fairly big and may be for a rifle. Long story short, not having a scale on hand, is there a standard size.. like a spent case in the hand gun family that will produce 15 to 20 grains of volume of fffg? I will alter the spout I have til I reach the magic number or hang it up and get a modern style one if I can find one. Thanks in advance ....FNG
