Any chance you know what the 10 bore nitro loading was for that rifle?

Mickey,
The standard 10 bore nitro load was 55 grains of revolver cordite and 920 grain bullet. I can only assume that was the load for that particular gun. There were a few odd variations in ignition and loads being used by Holland in some of their last 12 bore pdxes, to what end I am not sure, so there is always a possibility the same might apply with the 10's.
