I shoot tons of 9mm .45 ACP and 38 Spl. plated bullets as my range requires them, and here's what I do.

Lead data is completely safe to use from starting through max.

Jacketed data can be used safely if you reduce max loads by 10%. Of course that means jacketed data starting loads are fine as listed.

This is pretty much what Rainier recommends.

I also agree in not overdoing your taper crimp for best auto pistol headspacing and bullet to barrel fit.
