It would foul barrels but really no worse than gilding metal.
In some ways it is superior but a lot more costly than gilding metal.

Pretty sure that's the stuff used on a 7.5x55mm GP11 ammo for a K31 Swiss Rifle...projectiles are all silver colored.
Shoots awesome in my scoped K31, around 0.8 MOA.

I think you are correct David.
The Swiss weren't cheap about things.
Trivia,
DuPont found that a slight addition of tin to the powder completely stopped fouling with cupronickel.
The powders that had the added tin were the standard numbers with the addition of 1/2
There were a whole series of these DuPont powders 15 and 15 1/2, 17and 17 1/2.
If you ever run across one you'll know what they were. Rectangular cans made of brass with a dinky 1/2" screw on lid
