You can use any published data for plated bullets for the same weight and profile bullet, be it lead or FMJ.
Just start in the middle of such data, velocity will vary.
Here is what Berrys says (most plated are pretty much the same) Hi Tec coated bullets the same and they are less money and better than plated IMHO

Where can I find load data for your bullets?
Load data from any load manual or website can be used. Full-metal jacketed, lead bullet, or plated bullet load data can be used as long as the following standards are adhered to:
- The data contains the correct grain weight of bullet.
- Berry's max recommended velocity is not exceeded. (This info is displayed on bullet boxes and product webpages.)
- Standard Plate Bullets Max Velocity: 1,250 fps.
- Thick-Plate Bullets (TP) Max Velocity: 1,500 fps.
- Do not over-crimp the bullet. Crimping so tight that bullet deformation occurs, or plating is separated causing visible exposure of the lead core will cause tumbling, key-holing, and reduced accuracy.
Load data containing bullet descriptions such as Plated (P,) Berry's Bullet (BERB,) Total Metal Jacket (TMJ,) Copper Plated (CP,) or CPJ (Copper Plated Jacket,) refers to plated bullet data.
Cartridge Overall Lengths (COL) are found in the load data being used. DO NOT EXCEED SAAMI MAX COL SPECS.
