Great people, great products. So long as your bullets are .001" larger than groove dia. you shouldn't have any leading issues in 9mm or .40 S&W. And if you're going to keep your loads on the slow side, you can use the 12 Brinell bullets for .45 ACP. Haven't tried them yet, but I've had 0 issues with the 18 Brinell 200 gr. SWCs I buy from them and some of the loads are pretty light.
