Thread: 303 Cordite regulation load modern powder data

I'm just about to start reloading for a 303 double rifle

The regulation load printed on it is
Cordite 31 grains 210 grain Ball

Does amyone have any data that specifically is referenced against the old cordite data ?

I can easily work up the loads from scratch.
But a base line on what this cordite load was doing would be a good starting point.

Out of necessity i will likely use the Hornady 174 grain RN 312 bullet first up.
