I have used solid copper bullets. In rifles that have a high MV, they can work great, if your rifle likes them. There are lots of reasons not to use them, however. The most important reason is personal choice. If I don't want to use them, for any reason under the sun, that's good enough.
As for other states following the lead of liberal states that have outlawed lead, not likely in most states. The entire concept is nothing but an anti gun ploy to reduce the availability of affordable ammunition. Raptors are dying by the truckload in wind farms and the hippies are still ignoring that and crying about lead ammo.
