Gentle Readers:
I own a Gibbs 12 bore boxlock paradox gun. According to the Gibbs records - it was sold (not made ) by them in 1926 but they cannot tell me more than that It is proofed for 1 1/4 shot so it is a 2 3/4 inch gun and the flats are stamped for a 735 gr bullet. It came with a paradox style mould made by the previous owner and 25 pie crimped Remington hull cartridges containing a bullet from the included mould, thin plastic gas seal and fibre filler wads. The bullet is .729. I am told that he used 30 gr of sr 4756 for 1180 fps.
Of course, that powder is now extinct. Ross S. used 30 gr of unique in his paradox.
I welcome your thoughts. I would like to tip over a deer in the shotgun zone or perhaps a feral boar with it.

Thanks!
