My experience is the same as Walkalong's. I have been trying to work up a good load for their 130gr 9mm bullets, but it isnt working too well. They smoke slightly less than lead, but still smoke. I have used precision bullets in the past and dont recall them smoking as bad as the BBIs. Dave Long of Precision Bullets seems to be a pretty good guy. He has always been willing to answer my questions and emails promptly.
Even though the bullets are coated, i still get a little bit of leading in my Glock barrels. Its not really a big deal, just invest in a few packs of pure copper scrub pads (aka: chore boy) and use them with your bore brush.
