I’m now migrating from reloading from .38 & .357 to .32 S&W Long, .32 H&R Magnum and .327 Fed Mag. (Yeah, I'm back) I have Starline Brass, Powder and bullets, primers and a couple of load manuals. Here is my issue. The load data is organized by mostly: 85 Hornady XTP or JHP, 100 Hornady XTP, 100 Speer Gold Dot, 100 Speer JHP. Some older books have SWC or LRN, but I’m not sure I should trust the older data.

I have 85grain RNFP Plated and some Hornady XTP. What do I go by for the plated bullets? That is not a true jacketed bullet. Looking to buy some TCFP coated and what if I start casting and maybe powder coating?

I bought some Xtreme Defense and luckily, their site has load data.

General consensus is to use cast data for plated or coated bullets since they are about the same hardness as cast. Most plated manufacturers even state it somewhere on their webpage.

I use cast data for my own powder coated boolits.

It's important to start a new load, especially one that doesn't exactly match the published data, at the low end and work the load up.

I use cast load data for plated and coated bullets. Heavy plated bullets I treat like jacketed.

Lyman Reloading manuals are your friend.

Start with cast data for plated and approach jacketed if you wish and the plating holds up. With handguns in several cartridges lead data is greater than jacketed as the friction is less with lead. Compare bearing length if possible rather than weight.
