Yeats ago I stumbled across some data. I have no idea who generated it or how safe or unsafe it might be. I don’t have a 9mm Win Mag and have ZERO experience with it so take the following with a HUGE grain of salt:





The second image with more data won’t upload. Hang on….

That looks like the John Taffin (Taffin Tests) data.  See link.

I have several thousand rounds of new brass to load but I have yet to load any of it yet. There is a IAI currently on broker with all original papers. This is info that came with the gun so it should be a perfect load..
