I read little about the 'other' 375 H&H. Was it a common loading? I assumed it was released to the trades as the 375 belted was. I see that Searcy and Krieghoff load their doubles for itIf I'm not mistaken, Kynoch listed ammo in 235, 270 and 300 grains. Were the doubles regulated for one of the 3 loads? I assume what I know of doubles so far that it's unlikely that it would shoot all 3 loadings decently.

Is the Flanged case identical to the belted except for the belt? Will 375 belted dies work on the flanged?

It sure seems a good choice for a medium bore double capable of buff as well as large plains game and has the 'aura' that the 9.3x74 does not. Thanks for the upcoming info. Bob

Going from memory, I think it was a lower pressure loading to accomodate the inherent weakness of double rifles.

No Offense intended, but it has nothing to do with a 'weak double' and everything to do with
a high pressure causing sticking of cartridges,more than anything else. If you have done any reading
on pressures of doubles etc., you will see that they are almost, I repeat ALMOST always lower pressures
than that of a bolt action rifle. Although I have no practical experience in doubles vs rifles,
I have read extensively. The authors include Taylor, J.A. Hunter, Foa, Keith, Bell, etc.. The point being is it has do to do with lower pressures in doubles as vs rifles. Also I also have alot of
experience in reloading from .357 -44mag-30-06 to etc. and the knowledge of pressures
that one must have to stop from blowing one's self up if you get my meaning. I hope this helps.
And by no means take this as the end all to be all. Read as much as you can and ask questions
on this forum, there are quite a few individuals who will help.

The .375 Flanged is indeed the rimmed version of the .375 Belted case. Factory loading was in all three bullet weights. I have quite a bit of Kynoch in the .375 Flanged and all but two boxes are 300grn. The other two are the 270 grn. It is loaded to lower pressure and thus lower velocity than its brother but is quite sufficient in every way. It is quite a bit more powerful than the 9.3 x 74 despite what they say in Cartidges of the World. By the way C of the W is a lousy referance for non-american cartridges, except in a very general way.

The .375 Flanged was loaded by most of the English and a lot of the European makers over time and is not that hard to come across. Purdey loaded their own cartridge, the .369 Purdey which was a ballistic twin of the Holland in a 270 grain bullet. They made, I believe, 72 .369 Purdeys. According to Purdey a few years ago, they believed less than 30 still existed as the rest had been rechambered to the 375 Flanged. I have a friend who has one of the .369 Purdeys and because I asked about the quality of the rifle (it was made in 1942) compared to the pre-war rifles I was all of a sudden persona non gratis at the Purdey Shop. By the way the quality of the rifles made during the war was not as good as the pre-war rifles. I guess they had other things on their mind.

DBKing,
Perhaps you should read Graeme Wrights book on Loading the British double, 1st and 2nd additions...It is quite a nice book.

500 grs. is correct in his assesment and though your not wrong in your assessement, I'm not sure where your coming from...

As far as some of the books you quote, other than Taylor none of them had much information on the double rifle, but were tuned to hunting, and some of those authors didn't normally use a double rifle.

The 375 Flanged is basically a 375 H&H with a rim in simple terms, but it cannot be loaded up to bolt action pressures as it would surly shoot a double off the face or even split the soft barrels..Most are regulated to about 2100 FPS....
Yes, the 375 flanged was designed for the weak double actions of the day, and that is the bottom line.

Even today, it is folley to produce doubles in 416 and 375 such as Merkle is doing...Those guns are shooting off the face I have been told..Were I to purchase one it would certainly be in 470 NE.

BoBc, The 375 Falnged Magnum is one of my all time favorites for general hunting with a double rifle. One must be carefull when buying a used double rifle advertized as a 375 flanged! The reason being, There were several 375 flanged cartridges that are not interchangable. The 375 Flanged Nitro Express (2 1/2" ) is an obsolete cartridge that closely duplicates the 375 Win Mag, or the 38-40 Win. There was also a 400/375 Belted Nitro Express which is sometimes advertized as simply a 375 Belted Nitro Express,Leaveing one to think he is getting a rifle chambered for the 375 Flanged Magnum which is the flanged version of the common 375 H&H Magnum. The flanged version is loaded to about 100 FPS slower than it's belted counterpart @ 2400 FPS with a 300 gr bullet, compared to 2500 FPS of the belted bolt rifle version.

However if you are going to use your double rifle mostly for hunting in North America, and on plains game, and possibly the cats in Africa, then the 375 Flanged Magnum is a very versatile choice. I've had a couple doubles chambered for this cartridge, and I'm very sorry I sold them, as they were the best Bear hunting rounds I've used, the 9.3X74R comes close behind. This cartridge will "DO" for Buffalo hunting, though I'd rather have something a little bigger, if used primarily for that purpose!

Doubles, so chambered, are fun rifles to play with, and are quite easy on the pocket book when loading for them.

I was at a sporting clays shoot today where H&H had a display (and actually let people shoot some of the shotguns yesterday) ... one of the display-only guns was a double in .375 Flanged that fit me beautifully -- it hadn't yet been cut down & fitted with a pad.

Price was a little stiff at $125,000, though. For that price you could buy a thousand of their neckties. They also had a .500 NE, a bargain at $85K, I believe.

John Taylor had quite a bit to say about the.375H&H Flanged Magnum. He said the Holland's could build a double rifle that would be regulated with the three bullet weights at 100 yards (235, 270 and 300 grain). The flanged cartridge was loaded to about 50 feet per second less velocity in each bullet weight than same bullets in the belted version. Probably to ensure easier extraction in doubles.

Still, from the standpoint of the game animal on the receiving end, how much difference is there between the .375 Flanged and the 9.3x74? Since one can get a new 9.3x74 from Pedersoli for under $3K, does the .375 Flanged kill $122,000 better?
