Here in Canada, lead free is quite popular. I have shot almost all my deer with leadfree bullets, Barnes Triple Shock. I reload so it took a little time to get a good load for my 30.06. For my .243, the load data from the site was great. I honestly don't think that I will go back to lead. Last thought, copper perform well at certain distances and velocity. Look for the correct bullet weight when just starting. There is a sweet spot for full expansion.
Cheers,
