Small wound channels, poor energy transfer and poor shock generation -- looks like some serious downsides. Sounds like their use would require some "common sense" and some discretion and care whether or legal or not.

On the other hand though, what about folks that don't want to pony the bucks up for a bigger gun (or are recoil sensitive) for use on say, moose or elk -- wouldn't the use of solids allow them to use something like a .243 or 30-30 to penetrate in one side, through the heart, and right out the other side?

Good Luck and Good Hunting,
