He notes that the bullet is .255".
The .25ACP bullets are normally .251" but I dont know what a cast 25cal bullet would measure up as.

I might be missing something, but I still don't see where anybody says the bullet diameter is .255" I see that the caliber designation is .255, but with the Brits of that era the caliber designation was normally the bore and not the grooves. Thus, I suspect this is closer to a 6.5mm or .264".

Correct me if I have overlooked the obvious. I don't claim any knowledge of this round and had never taken note of it before this post.

That is in Greenwood's book.
I know what you are saying aboit the british cartridges but there are exceptions such as the 416 Rigby, 333 Jeffery and the .300 Rook for example which are also designated by bullet diameter.

The .255 Rook Rifle ctg. (COTW) looks similar to the modern .25/20 Winchester. It is listed as small,rimmed, necked cartridge introduced by jJeffery and used in Rook-type rifles.

Small game and target number with 2 loadings, 9 grains of BP or 4gr. of smokeless - both with 65gr. lead solid or HP at about 1,200fps.

This round is listed as having a .255" bullet diameter (lead bullets to .257" would be just fine, if not perfect - depends on the chamber, of course).

The case is very, very close to the dimensions of the .25/20 Winchester etc. and undoubtedly, modern .25/20, .218 Bee or .32/20 brass is virtually perfect for this rifle's chamber - necked to take a .255" to .257" bullet, of course. It would surely be a fun gun to own and shoot and in that rifle, the ballistics could be improved upon some to make it even more fun as a small game iron sighted rifle.
