2. Ah, why is this? People seem to do both with 777? - 777 is NOT black powder, nor is it used in any form of MLAIC competition, which categorially states that BP only is permitted. 777 has a FAR higher flash temperature than BP - hence the name. It is not considered to be a Class 1 explosive like BP, but a flammable propellant, and can even be metered like regular nitro, according to Hodgdons loading manual

4. I have ballistic spec spectacles as my normal eyeglasses, do you mean more than that? - Nope, if they are proper ballistic spectacles, then are good for protection against the inevitable BP cap fragments.

5. No mould, I would like to cast my own or ideally get someone to cast them for me whilst I drink coffee and have a smoke. - I cast all my own bullet and ball simply because it's fun and cost-effective. Seeing the price of Pedersoli .451" ball at around £12 - 14/C just gets me annoyed - I can make them for about 1/8th of that.
