The Certus does have a following here.

Her's a thread on Ash's 450:

I wonder if the barrel was originally a 450/400 barrel and was rebored and reproofed to the light cordite 450 load.
Looks really thin with a LOT of taper at the breech.
Anybody here know what the original Certus proof load was for the 400?



According to the Fleming book the .450 3 1/4 Certus load was 65 Cordite 440 Grain bullet.
The pictures of the barrel do show the original .450EX proof with the 65 Cordite visible but the “440” bullet weight overstamped.
Maybe a later reproof at 45 Cordite and 365 grain bullet because the original Certus load was no longer available and the common 70 Cordite 480 Grain bullet DR and Single shot loading was too much or would not fit in the magazine?
Would have to have the barrel out of the wood to see if their are more marks under the wood.
