I've shot 10s of thousands of plated bullets, 38spl, 357mag, 40s&w, 45acp, 10mm, and even 30 Carbine with great success. The 40 and 45 were through stock Glock barrels and I've never had a bit of leading, some copper that needed removing after 5-6K rounds but not a single bit of leading. And, you can shoot plated bullets significantly faster than the mfgs claim. My 158grn plated 357mag loads are chrono'd at 1,822fps out of my 24" Rossi levergun and they fly out to 300yds without any problems. Pretty accurate too as at 200yds I shoot at 8" steel plates with my 20" carbine. Load them with care and they behave just like lead but without the mess.
