Ah totally agree.my brother is a falconer and only takes steel shot pigeons.He too uses his birds for buisinessBeen using Barnes ttsx in for while now and in my air rifles for longer (lead free) as we as a company fly hawks and work ferrets the ferals and some rabbits we air rifle can be fed to the hawks. Lead will kill a hawk in very little time. I’ve had it once. Fed up on a bunny that a hawk caught unfortunately it had been pricked with some lead shot (shotgun) and the hawk ingested two pellets. It died 2 hours later!!!!
I even use lead free 17hmr now as well. Apart from cost I’ve found no difference in meat damage and accuracy. Although they need to be driven faster. I use factory mainly some homeloads if desperate but I’ve just collected 180 creedmoor and 140 .308 and the same in .30.06.
my foxing is a v max .243 but when I’ve used my rounds up I have then I’ll change as well. Given that most (not all) but most foxes are thrown in a hedge etc after the event this could lead to secondary poisoning to scavengers eating the Carcass
