Havent got a clue about Forestry commission etc - But if they are talking about non-lead bullets they are probably refering to the use of alternative metal projectiles to negate any environmental issues from people pumping 100's of grains of lead into their soil.
Have a look at BArnesX bullets they do an all copper bullet. They are not the only producer, there are plenty of non-lead bullet manufacturers but you will notice a cost increase over standard jacketed lead bullets.
Several manufactureres also market green ammo that uses non-lead bullets and even non lead primers - I guess it comes down to two things, what calibre rifle do you use (and does anyone manufacture non-lead bullet rounds for that calibre) or do you reload in which case you can more than likely get non-lead bullets for reloading in most calibre's
