You do not have to limit Raniers, Berrys, X-Treme, or Jakes Powerbond bullets to lead data. Plain and simple. There is data for plated bullets out there.
Accurates PDF and
Vihtavuoris PDF files available on their websites have some. I also attached an old Midway PDF for plated bullets. (Same data as the Ranier link if you click Midway)
Here is a link to the
old Ranier data You can click on the Accurate data, Vihtavuori data, or Midway data for plated bullets.
The Powerbond bullets are the toughest of the ones mentioned, and can be shot at pressures and velocities the others can't take. In my testing they can take jacketed data with no problem as far as damage to the bullet, and are very accurate. Pressures that will result? I dunno.
