Hello Ben,
Beautiful rifle.
I do however caution you on the portability of Marrakai's load.
He describes his rifle as being a Cordite Express gun.
If that's the case, it was built and proved for a Light Cordite load. Those were not the full Nitro load (never existed for that round IIRC), but were still much stronger than the BPE load.
Your gun is most likely to be a standard BPE gun, than a light Cordite one.
So, caution is advisable! You probably should invest in a SW like Quickload to gauge pressure on intended loads before pulling the trigger.
Best regards,
WC-
