    I've been trying to work up some loads for Hornady 147gr XTP, and was pointed to a Lyman load listed in the 49th--a load for the Speer TMJ 147 gr.

    What I'm wondering is if it's more like the Rainier Leadsafe plated bullets, which I load more like lead, or a harder shell more like a FMJ?

    They are jacketed. TMJ = Total Metal Jacket...similar to FMJ which is, of course...Full Metal Jacket.

    Speer TMJ bullets are plated. I've loaded them hot enough to prove it (45 Super)

    Hmmm, after looking at their website, I believe you are right, but they are not plated bullets in the usual sense. They use a much thicker "jacket" with better bonding than Ranier or Berrys etc. They use this technology on several of their bullets designed for tough duty. It is a proven bonding system. I am surprised you could make them fail. They will definitely hold up to standard loads in 9MM.
    More like a FMJ, designed to be loaded with standard jacketed data.

    Agreed.

    The Gold Dots are the same way...I've seen those come loose with hot loads too.

    ...and, IIRC, the Speer TMJs (including 147-gr) I bought some fifteen, maybe twenty years ago are jacketed and not bonded. AFAIK, the Gold Dots have always been the bonded type. Some of my testing with the GDSB 135-gr. JHPs yielded fragmenting when loaded above perhaps 1200--i.e., MAX 357 loads, 4" barrel.

    Thanks, guys. I had had hopes that the bullet was more like lead than jacketed, but I'll simply accept it as FMJ and go from there.

    The Speer TMJ and Gold Dot bullets are made by electroplating copper over a lead core.
    BUT the plating is about three times as thick as what the "plated bullets loaded like cast" from Ranier and Berry have; so they are loaded like drawn jacket bullets.
