sj,
I'm sure the primers are corrosive as well. You could always test by pulling a bullet, dumping the powder (I have never heard of corrosive powder though),
and firing the primed case toward a piece of cleaned steel (safety glasses on!).
I treat all Chinese ammo as corrosive anyway.
If they are willing to ship us children's toys with lead paint, I figure they do not mind fibbing on the priming compound.
I agree that it would be most economically effective to sell the ammo and purchase .308" bullets for reloading in a .308 caliber gun.
If you are also reloading for the M43, you could pull the bullets and re-use them to eliminate the corrosive effect.
One could not, however, count on just transferring the powder from the berdan case to the new boxer primed case especially if the original cases are steel.
The steel cases have greater capacity than brass, and you could get into pressure issues.
I would also refrain from pulling all 900 rounds and dumping the powder together for reloading back into your new cases.
Even though the ammo is in the same case, you might have different kinds/lots of powder in there.
I've experienced this in sealed cases of Yugoslavian 8mm.
Both of the outdoor ranges I belong to out West do not allow the use of steel core, as that ammo was directly attributed to starting several fires.
Getting caught with it at one of the ranges will result in permanent expulsion.
