be warned,lead bullets in a Poly barrel are a manufactors no-no.though,I have done it without any problems. jwr
Not all manufacturers say lead is prohibited in polygonal barrels... some do, some don't. I only have the manual for my CZ83, which also comes with the polygonal barrel in it's 9mm Mak iteration, but only says limit ammo to factory ammo certified by CIP or SAAMI. No specific prohibition of lead.
