No way to answer. Find a good gunsmith and have him examine it.
Less than .01 cents
yes. as wild desert tortoises get older the color of its shell gets lighter color if dark when young.
You cannot change the color of the egg shell, genetics are pre determined at hatch and the color of the shell is not effected by feed. You can change the color of the yolk with feed but not the shell itself. The color of the shell is due to a bile duct secretion as the egg is forming in the oviduct of the hen.
The same as it is before it's fired - a casing. Some refer to an empty casing as a "shell" or "shell casing".
