I believe Holland kind of searched for a "normal" paradox 10 bore load upon introduction. You find several 6 dram and other anomalies in some early guns. They did settle on the 10(9)bore 2 7/8 case 8 dram load with a 900gr+ bullet at 1465fps. That is the load that they duplicated with cordite for their nitro paradox 10(9) bore, the last to made in 1929. One other note, all the Holland 10 bore rifles and paradoxes excluding the Julia gun I have seen (more than a dozen)have had dished actions, many made by presumably Scott.
