Everything affects them. 
Temperature biggest affect as far as weather. 
Altitude, wind, humidity, barometric pressure, moon position, tide going in or tide going out, cloud cover, amount of sunlight .
Think lead affected more by temps. (Density) 
TSS more affected by wind .  ( lighter weight)  
Bore size, Overbore/backbore lose more in cold but gain more when it's warm.   
That being said no two patterns ever exactly 
Wind. Think TSS drift a little more than lead as far as turkey shot size ( pellets lighter).
