Martini Henry cartridge identification

[RCS]

I have posted a photo of three cartridges that were used in the Martini Henry. The first cartridge 577/450 has a coloredAttachment 89491 green band at the base of the lead bullet. Could this be a carbine loading ?

The small middle cartridge is the 297/250 Rook and the far right is the very early cartridge

The carbine loading is distinguished by the coloured patch and the shorter (lighter) bullet. I have seen these patches in blue and maroon as well. The MH carbines are 'interesting' to shoot a few rounds with standard rifle loads!

The green pp signifies a cordite carbine load in solid case.
The coiled case looks like a MkIII coiled rifle ctg. The MkIII is distinguished form the earlier marks by a sight hole about 3/4" from the back of the case.

Been there done that Woodsy, they kick like a rabid mule in a
Very bad mood with the rifle load!

The Patch codes are, as I recall:

White - Rifle Black Powder
Yellow - Rifle Cordite
Red - Carbine Black Powder
Green - Carbine Cordite

are you sure that is the .295/.250 Rook? It looks more like a .295/.230 Morris which was used with a subcaliber tube for the Martini!

The reduced carbine loads were achieved by using a roll of thick card around the side of the case to make up the volume with a lighter load. This is a much safer solution to case volume reduction than using wads, fillers or other in line obstructions that could cause pressure peaks. I am surprised this practice does not seem to have been taken forward...

To re-vitalise this thread, I am intrigued by this:

If anyone has tried this method, I'd be very keen to hear how they did it, and what happens when reloading?

Sorry, duplicate

I place two wraps of nitrated paper in my cases followed by 75 grns of 2FF. It brings the powder just up into the neck so that I need a slight amount of compression to make it level at the base of the neck. A grease cookie between two card wads and then the bullet. I rarely shoot past 75 yds so it is a pleasant load in a full size rifle.

Bombdoc, you are correct, the small cartridge is the 295/230 Morris short

my example is early without a headstamp
