I have used them in the past and they were fine - a bit soft though. A few years back I started using Penn's Polymer coated bullets. They do cost a little more but have no lube (doesn't need any) and therefore smoke a whole lot less which I really appreciate when shooting indoors. They are also a lot cleaner to handle and I no longer have to deal with lead all over my hands and dies. They seem pretty accurate as well.
If you shoot mostly outdoors lead works OK - just wear Nitrile gloves when handling them and wash up thoroughly afterwards. I've still got tons of lead bullets in my inventory to load.
