Its just like gun guys who want to feel superior in their ideas to say some fairy story they have been told and tell is true. I know many Glock owners who swear that their tumors went away after touching a Glock. Many say after shooting this or that brand of gun their impotency was gone. I some how doubt it very seriously.
Aluminum and steel do not work just as well in many weapons as brass does. You will have a hard time arguing with physics.

That has not been ANYONE's experience that I am aware of. Here is what a copper bullet from an M4 looks like after hitting game.


The TSX and GMX rounds are great, and have seen use everywhere from Iraq/Afghanistan, to ranchers culling pigs. They are very popular in Africa, as well, with many hunters finding that they can step down from the belted magnums to the .30-06, for some game, due to increased lethality and penetration of the TSX/GMX rounds.

Eco-friendly or not, they simply kill stuff dead fast.

You are correct, but it's because people are comparing relatively cheap solid copper practice bullets with expanding lead hunting bullets. Specially designed expanding copper hunting bullets perform as good or better than lead; they're just more expensive.

Yes.

A case has to do two things very quickly: Expand at the instant of firing to seal tightly in the chamber, then it has to contract the instant pressure subsides so that it can be extracted easily.

Brass does that. Steel and aluminum have a tendency to expand and not contract (case-form), which causes extraction problems. You can case-form with brass, too, but it takes a lot more pressure to make brass "take" the form.
