WWB specs.: 115 grain bullet at 1,190 fps.

NATO Military spec.: 121 grain bullet at 1,260 fps.

What you are suggesting as the problem should be just the opposite, that being, that hotter ammo should need a heavier spring, not a lighter one. Make sense?

Thanks!

First off, I am not Dave. Secondly, the Luger toggle action reciprocates in proportion to the bullet's momentum, not its muzzle energy. That's why WWB works so well with the original spring rates -- for everyone else, but not for me.
