Could someone tell me what calculation I need to do to work out what pressure i need to apply to my 2" pucks to [font="arialhelvetica"][size=-1]get to density of 1.7 grams/cc.
The pressure is not important, you need to calculate the volume of the finished puck (with a known weight of DRY powder). Area of 2" puck is 20.25 cm2. If you make the puck 1" thick (2.54cm) then the volume is 51.435 cm3 x 1.7g= 87.44g of BP needed.

thank you for working that out for me. 87.4g im just imaging that igniting while being compressed .
well i took plunge and pressed one out at 6 tons.
very impressed with the finished product. will give it a couple of days to dry, and will post if my black powder has improved
