We have also moved away from lead at the Wildlife Trust sites.

I am afraid to say you are wrong on this one and Ill explain: A bird of prey is not a Chicken or Duck, it does NOT have any grit in its gizzard, doing so would likely kill it.
In layman's terms A bird of prey eats the meat, including bones etc that are either swallowed whole or broken up, this passed into it the first stomach where acids and enzymes break the meat down, this mass is then passed into the second stomach/gizzard where it is crushed by the muscles squeezing the liquid out which is then past further down, whilst the waste in the form of fur, bone etc is coughed up in the form of a pellet. Problems arise when the meat contains regular spherical shaped pieces of lead, eg fishing split shot and shooting shot, this cannot get coughed up because of how the muscles work etc, but irregular lead shards easily mix with bone and fur to be coughed up. Friend I have who use birds of prey will happily feed rifle shot meat, rabbits and deer etc, but never shotgun shot game. Another thing that might interest some is the fact that if to many lead pellets are in the gizzard, the birds often die because they cannot squeeze the food from the first stomach and starve to death!
Anti shooters will say anything in Komifornia. I think lead bullets are to be banned there from next year?It's not lead shot that has been an issue with raptors in the US & condors in particular; it's lead fragments in gut piles from bullets.
Study from California here.
Unfortunately the noise made by the antis can often obscure very real issues.Anti shooters will say anything in Komifornia. I think lead bullets are to be banned there from next year?
Thin end of the wedge to ban shooting altogether.

Thanks for the replies guys....the lead issue in my case perhaps deserves a seperate thread though! So effetively there is no definative answer to this question. Perhaps an answer along the lines that gralloch should be disposed of on a site by site basis dependant on public access and the land owners wishes taking into account water courses etc
Hide it, bury it, do what you like with it, some wee beasty will dig it up, find it, eat it.
The effects on raptors of lead shot or bullets from carcases and carrion have been documented ad infinitum.
there is nothing open to interpretation.
I could quote numerous scientific papers from California to Scotland
They do not magically expel it without absorption.
Simple answer if you don't want to leave lead in the environment.....
dont use it...
We do a fine selection of non lead ammunition and bullets
The reasons FOR outweigh those AGAINST by some margin
Accuracy? Significantly sub MOA
Terminal effect? Outstanding results across all U.K. Deer species
Carcase Quality? Significantly improved, less shrapnel, less sub cutaneous and intra muscular blood clots.
Ricochet risk? Recent impartial study concluded "no significant increase in risk over lead cup and core"
Cost? Same as or in some cases LESS than a box of mid to premium lead ammunition.
97-100% weight retention
you bullet is in the ground
not the carcase
its the whole point....literally
The first 5 posts dealt with this perfectly until someone wanted to talk about lead & raptorsBloody amazing.
Read the first thread of what the lad wanted advise on and then read the one above this one. Talk about going around the houses. I hope Liongeorge can work it out.......

Aren't there twist rate issues with .243 & copper? Nosler recommend a rate of 1:9 or faster for their E-Tip, but many .243 barrels seem to be 1:10.
I'm not criticising the environmental soundness of using copper rather than whether gun & ammunition makers are properly coordinating on this.

Thanks Alan tried to get it back on track a while ago ...doesn't seem to be working![]()
You will never see a 100gr 6mm/.243 non lead bullet stabilise in a 1:10" twist barrel sadly
Just not possible due to the length
The .243 was never designed with 100gr in mind
Its the poor choices of minimum weights and calibres in the Deer Act that cause the issue in Scotland and Northern Ireland
Outside of this anomaly pretty much all other standard loads are fine.
TTSX and GMX suffer with twist issues due to the boat tail and ballistic tip increasing comparative length.
Flat base bullets do not.
