Hi all,

How much lift should be used in bag mines (mines to be fired from a mortar), as a percentage of the 'load' ? I have only made 1" mines before with their own tube, and I use about 2g of powder for lift. I want to make some 2" or 3" mines, with coloured and silver stars, any suggestions?

I had been using 14g of 2FA in a 50mm mine and 18 in a 75mm mine using perforated discs as pistons

In a 3" I tend to use about 1/10.

I haven't experimented with it a great deal so I don't know if that is "optimal" but it looks good to me.
