Fibre wads can be made from fibre board used in the building trade when concreteing.Wad lubrication can be hot beeswax or vegetable oil just put the wads in a wire mesh fryer pan, dip into hot oil for about 30 seconds and then let them drip dry cool.When loading, ram them to a pressure of 50lbs or 75-80 for black powder.I use a 1/10inch overpowder card, fibre wad, 1/16inch card, shot load and then a crimp closure or a RTO for my posh BP game rounds.I have used 3/8inch thick cardboard wads with out any adverse results (cheap to make) but my 'posh' BP shells use fibre plus a felt disc punched with a wad punch out of old felt hats (I find French berets the best, maybe you can use Canadians?)
