Plated bullets are not jacketed bullets.
I don't think anyone in the thread is confusing the two.

They use cast bullet data.
It's not that simple. That is one of three common guidelines for loading plated bullets. It makes sense from the perspective of hardness and resistance to elastic and permanent deformation of the bullet in the barrel. In terms of lubricity and pressure potential related to lubricity, plated bullets seem to perform closer to jacketed bullets.

The other two guidelines are: Keep it under 1,200 fps and use mid-range jacketed bullet data for a similar weight and profile.

Sometimes these guidelines are mutually exclusive.
