Yeah and some states like CA where I think the first to bring in state laws to ban lead a long while back . That really boosted Barnes and now with products like the tTSX is most likely the biggest . Personally i started with copper when the FC started to put the guys into none tox . Now its spreading all over the world ( although brass solids etc have been used on large and dangerous Game way before anyone of us was alive, let alone shooting anything )
I think the fact that the Chinese now own the majority of the copper rights in the like of Zambia , we might see even more alloyed new products for bullets ( oh China buys the biggest slice of all the worlds scrap metals )
