Just run it as 124grain jacketed. 4.1min 4.6max 1.090 min oal. Plated is typically ran as mid lead to low jacketed. So lead would be 3.6min 4.1max... I guess start at 4.1 and watch for pressure signs and adjust accordingly. I ran into that kind of problem with loading .40 and just did 10% under jacketed data. Which normally lands you in the max range of lead.
Thanks for the suggestion. Its too bad that with so many copper bullets out there they can not give better data.
I'll bet a few years from now you will find lots of plated data. They have not been too popular until reciently.
How did you find 7625? That has been hard to get for a long time. Old Skeet shooters like it in 20/28 gauge shells.
Glad you found some, it will probably do pretty well in the 9mm
