Hi all,

I have been firing my Remington 1858 with triple 7 powder loading directly from my powder flask which has a nozzle which I believe is supposed to measure 20 grains by volume. I also have a nozzle marked 15 grains. Now I have just bought a scales for starting reloading and I decided to test it out by finding out what the charges I have been using in my bp revolver weigh. This is where my confusion lies, I have been getting 12.1-12.2 grains on my scales for my charge which is supposed to be 20 grains. Also with the 15 nozzle I'm reading a lot less. The only thing I can think of is that the volume measured is marked for black powder and that the same volume of triple 7 weighs less, however I thought that this was not supposed to be the case with triple 7 but is with other powders like pyrodex? I have tried weighing several times and the scales are giving the same consistent readings. Anyone know what's going on?

Cheers, Mark
