The copper jacket is needed to push bullets at very high speeds and to withstand the very high rpms generated by the rifling. A lead bullet would fly apart because it is too soft. The harder copper jacket keeps the bullet in one piece.

How do you do copper coating on iron powder?
Contacting the iron powder with an aqueous solution of copper (II) salts will produce a copper coating on iron powder: Iron is higher in the electromotive series than copper and therefore will displace copper from the solution, resulting in copper-coated iron and dissolved iron cations. When all of the surface of the iron powder has been coated with copper, the iron will stop reacting because it no longer has access to the copper ions in solution, the access of the iron being blocked by the layer of copper coating the remaining iron powder.
