Hi folks

Am looking to find information on the calibre .500 x 2.5 inch BPE
I have recently acquired a double rifle by James Beattie (London), c.1864, in this calibre and am struggling to find any info on this at all.
Suspect the rifle was made for British officers in India for sporting purposes being a .500.
The only calibre I can find similar is Sharps .500-90 STRAIGHT.
Will keep you posted once the rifle arrives with me, and have considered a chamber cast to check when it does to confirm dimensions. .500 x 3 inch would make more sense as is same as 500 Nitro Express.
I do plan to reload for the rifle if possible and seems it deserves to be shot if condition permits.

Any help much appreciated, I've waded though many cartridge catalogues and not yet found an exact match but thought this is something Double-rifle aficionados will be more familiar and nuanced with. Any help/steer much appreciated.
Pics will follow

Cheers

Let he who casts the first stone - be accurate.
If he cannot be accurate, he should practice first.
