Ahmed,

Patience is quite a virtue.

As nobody makes 10b Paradox ammunition at present, have you decided what ballistics to specify for regulation?

My 10b was built for the 8 dram load, which used a 2 ounce (875 grain) bullet in a 2-7/8" thin brass case, resulting in approximately 1500 fps. I don't think there was much change in ballistics when the round was adapted to nitro powder. I am buying cases from Track of the Wolf, but I see they don't export these. https://www.trackofthewolf.com/Categories/PartDetail.aspx/1210/11/SHOT-SHELL-10-2-78

I'll be interested as this project continues to develop.

One last question: Why would you have Purdey build this rather than Holland & Holland, the traditional Paradox maker?
