Bayou #1
Missouri #2

I've push Bayou bullets beyond the point that plated bullets break apart in flight and they have not only held together 100% but still don't lead up the barrel.

Missouri. I've actually just started using them. I'm very impressed with the quality so far, but Donny at Bayou is a heck of a lot more entertaining to talk to on the phone.

I'm not discounting JMW's suggestion, I've simply got zero personal experience with them . . . so far.
