One question, why?
After comparing price for plated, lead and coated bullets - My conslusion for 9mm, is that Extreme plated is as cheap as the other alternatives (considering, tax, shipping, etc)
For .45 ACP I have a local supplier that sells lead 230 gn for $10 per 100 (inc Sales Tax). That is somewhat cheaper than plated Extreme, but not really all that much.
Since, the .45ACP 1911 has standard riffling, I found that shooting lead was OK but certainly more smoke. So, I am still undecided as to if it is worth the difference in price. However, I have not found coated bullets that would provide any price advantage to plated. What have I missed?
