Thanks for the photo!
That's a great looking mould. Great story too.
I don't recall whether or not you've reported taking game with roundball in that rifle. At that weight and velocity it really is a ripper for sure.

Blue Dot?
I've spoken with JAZ and Gatsby and others about this, but haven't taken the plunge in any of my bore rifles yet. I'm not running such big diameters and charges though - but will likely some day try the Blue Dot in my big-case sixteen bore WR double rifle.
Have you had Armbrust do back to back comparison of BlackPowder and Blue Dot on loads for your rifles?
I'd love to hear the results if you have pressure data.

Cheers
