    In regards to the question of titanium bullets and if they are manufactured. As far as I am aware no one produces that kind of round commercially. Especially not for civilian use, however; I have been making several different rounds for the 9mm, .357 mag, .45 lc, .45 acp, .223, 7.62x39, 7.62x54R, .308, 30.06, .410, 20 ga., and 12 ga. in different alloy's. Most of what I've been using has consisted of is titanium, tungsten, chromium, iridium, tantalum, and iron. The results have been quite impressive.
