500 Jeffery-Original Cordite Load??

[uplander01]

Would there be anyone on here that has access to an original 500 jeffery that would be stamped with the original Cordite load charge. Thinking I may try and duplicate it with IMR3031 like I do in double rifles, and see what happens. It has worked for other calibers I have tried but I can't find anything that list that original cordite loading,....and there are very few original 500j floating around that would have the stamp.

Thanks-

It was never loaded in Britain and therefore never loaded with cordite. Have a look here:

Let’s face it: double rifles are not for everyone...

The more I search that seems correct. However, I did find a thread on a ntitro express forum that a guy posted, that in the 1960 Gun Digest, the 500 jeffery was listed among a bunch of other calibers with their original cordite load, and he claims it says 95 gr Cordite. That would seem to make sense as when you do the cordite /smokeless conversion it would come out to 101 grains of IMR 3031. That is commensurate with the load charge for many other powders I've tried. Pretty similar burn rate to H4895 which I haven't tried either.

The Woodleigh loading manual is a fantastic reference document . Always interested at how long the barrels were to achieve the reported performance . For example 26 inches for the 505 G and 416 Rigby and 28 inches for the 425WR .
