If anybody has any ammo or brass, would really like to buy. I know one used to to be able to send brass to Hornady and they make you dies for it. Got a friend of mine that ended up with Arisaka riffle chambered for that round.

7x54 Finn, or MAS? The Finn round is just a necked up 6.5x55 Swede. The MAS round is the French 7.5 necked down.
The Finn rifles of the WWII era were modified Soviet/Russian Mosin-Nagant of the Model 1891 succession, using the Russian 7.62x54R cartridge. This cartridge is fairly common. I have purchased new ammo made by PRVI Partizan from a couple different vendors, though a quick google search shows many currently out-of-stock. The French 7.5x54 is a different cartridge altogether. The Finn round is not a necked-up 6.5x55 Swede, which is rimless. The Russian 7.62x54R is a rimmed case.
7x54 Finn, the necked up Swede is the one that I am looking for.
7 x 54 Finnish (Sako and Lapua)
From Wikipedia, the free encyclopedia
7×54mm Finnish
The 7×54mm Finnish is a rifle cartridge which was designed by Lapua as a moose hunting cartridge. It was loaded by two factories, Sako and Lapua in Finland from about 1944 until 1974.[1] It is a 6.5×55mm SE necked up to take a 7mm (.285) bullet. It may be loaded with modified 6.5×55mm SE dies drilled to fit 8mm neck diameter. It was usually loaded with a lightweight bullet.
Dimensions were measured from a cartridge loaded by Lapua and from (if two measurements) a case that had been shot with an modified Arisaka. Because caliber is a wildcat, those can vary greatly. Rim diameter of the 6.5×55mm is 0.480" (12.20 mm).
7×54mm MAS
In 1948, the gunsmith M. Jean Fournier sold some hunting rifles based on the MAS-36 rifle and the 7.5×54mm cartridge Mod 1929. As the French public could not use military cartridges, it was made possible in this case by reducing the caliber to 7mm, keeping the rest the same.[3]
Not to be confused with the 7×54mm Finnish, the naming is similar but the cartridges are not compatible.
** There is also a 5.7mm variant which was used for 'running deer' contests.
A quick look did not turn up any brass for your cartridge from a factory. You could contact PPU in case they only release it to the European communities.
You can neck up 6.5x55 brass to achieve cases but the head stamp will be wrong obviously.
Best.
RCBS used to have a custom shop, originally run by Roy Huntington himself after he sold RCBS, called Huntington Die Specialties. I don't know if they are still around, but they used to make custom dies for unusual cartridges. They were expensive as most were one-offs.
Still there, but business has been interrupted by the fires and Covid lockdowns.
My misunderstanding! I live and learn here!
Hornady does the same thing, already done some with them. I think they needed three shot brass.
