The 7.62X39 will do as you ask it to do. You can get a 123-150 grain bullet that will work well for you. The Z-max, is the V-max varmint bullet, not a deer bullet. That being said, saying a 7.62X39 is a carbon copy of the .30-30 is like saying the .308 is a carbon copy of the .300 H&H magnum. It is not close unless you call 3-400 fps. close.
