Am about to put powder and ball into cases to make the Martini-Henry MK IV speak for the first time in over 100 years. Have run upon a puzzlement that maybe one of my fellow THR members can help solve.
The modern smokeless powder weights are all based on 7000 grains/lb and are all actually weighed on a scale. Black powder charges are usually referred to in grains by measure...which uses a measuring device made for the powder. But, when set to 85 grains it throws more...by weight than it says it is.
My question: When the old British manuals say the charge was '85 grains', are they actually referring to a volumetric equivalent and NOT the measured weight?
This is my first Black Powder Cartridge loading endeavour and I'm committed to doing it right. Thanks for any help.
