Weirauch HW80K vintage???

Billbob, I’m not so sure about that story. The additives in pellets are usually very small amounts of tin and or antimony.
If I had to choose I’d probably take Tin over lead, but I guess neither is the best option.
One advantage of an air rifle over a shotgun is one largish pellet vs many small or even tiny shots.
Much easier to find and pick out, or spit out 😂

I’ve spoken to a vet about this with regards to dogs or cats ingesting a pellet in a carcass, and the vet reccons:
1- the pellet will pass through the animal and come out with the poo in a few hours, so not a problem.
2- if it’s only one or two pellets once in a while, no problem, if it’s multiple a day, every day that might lead to problems.

The reason they have banned lead shot from water fowl hunting is quite different, and once you understand how a birds digestive tract works you can understand why lead has been banned.

Birds don’t have teeth to chew and break down food like we do.
They swallow food whole. It can be stored temperariy in a crop, and/or then moves to the gizzard where muscular action grinds it down. Birds often swallow small stones which stay in the gizzard and assist with grinding the food before it passes further into the Intestines to get digested.
The way Ducks and waterfowl feed is on aquatic vegetation and algae, if there is small lead shot on or in the vegetation the ducks will ingest it, it will then sit in the gizzard and help grind food, but will also slowly get ground down so the duck is ultimately eating /digesting tiny particles of ground up lead shot over a long term.
As apposed to a dog who eats a rabbit with a pellet in it, swallowes one large chunk of lead pellet, and will poop it out 6 hours later.
