Weakest modern 7.63 x 25 rounds?
 

HI Guys:
Long time absent, glad the forum is alive.
I have a question now.

Of the modern manufacturers of Mauser 30 ammo, how would you place it from the weakest to the most powerful loads.

I am under impression that Fiocci is the softest of them all.

The reason I ask, I might be getting me a unicorn of early semiautomatic pistols: Schwarzlose 1898. It was supposedly known to use Borchardt and Mauser 30 rounds.

Borchardt is weaker , I believe, but is nonexistent unless hand loaded?

But the weakest commercial round probably would be the right thing to do- trying to shoot this old and valuable piece?

Thanks
