Saw Nosler loading for it. What is it capabilities specs etc?

I read about it long ago. It was developed to be a better case for the old single shot & double barrel rifles than the belted .375 H&H.

Loaded to a bit lower pressure & velocity than the belted .375 H&H version as I recall.

Sorry, that's about all I've got...

"Cartridges of the World" lists the .375 H&H Flanged at 2620 fps with the 270 gr SP and 83.0 grs of IMR 4350. They also list the 300 gr bullet at 2500 fps loaded with 80.0 grs of IMR 4350. The flanged loads are listed at about 100 fps slower then the standard .375 H&H, probably because of the age of the double guns made for the flanged cartridge.

I would be very cautious in loading for these old doubles, as that partiticular cartridge has not had guns built for it in many years.

I was getting fitted for a rack grade Chapuis 470 nitro double rifle at Champlins in Enid, Oklahoma some years ago and they let me go through the gun room. Wouldnt you know it, a 375 flanged Rigby fitted me perfectly. Comb, heel, drop, everything just like the try gun. Only problem was it was made for a Mahrajini (a lady Maharaja) in India in the twenties and cost $100,000. Never mind. BTW, They are a great resource for reloading the double rifles. Loads are reduced slightly from the H and H mag not because of age of double rifles but because they are double rifles which operate at only 40,000 - 45,000 psi or so. Ejection is not a sure thing with a belted case since the extractor can slip over the rim. A flanged ctg does not have that problem. I use to carry a rigid cleaning rod with my Ruger #1, as I loaded it kind of hot and occasionally the extractor would blow past the rim and you had a stuck case. My bad as much as the rifles, but not a confidence builder in a dangerous game rifle.

Thanks guys. I had just never heard of it and was wondering what it was.
