Ok, didn't know they were plated. Never used Berrys and it doesn't say it on the box.. Been shooting 200 gr. SWC lead that are always externally lubed. Can't help with the 9mm stuff, but is there anything else you're after? I have 1200 rounds (3 boxes of 400, unopened) of New Browning 40 gr. 22 ammo I'd swap you for the Berry's bullets...its around 1200+ fps. And too hot for my old High Standard pistol...
