Yes, the CX 4 in 45 acp will eat lead bullets all day long. I load 200gr cast lead at 1000 fps and have shot several hundred in my CX 4. No sign of leading and no failure to feed or fire. Hope this helps.

Lead
A better question would be which do NOT have lead. A small percentage of rifle and handgun bullets are solid copper, bismuth, or some non-lead metal. Shotshells used for waterfowl are loaded with non-lead shot- steel, bismuth, or iron/tungsten alloys. But MOST bullets are still lead. It may be covered by a gilding metal jacket, but it is there.
they use (Lead) because it has a low melting point and easy to mold and cool. they also use it because it is light enough to be shot farther but it also has enough weight so the wind wont affect its accuracy as much Lead is used only in cheap bullets. Better bullets are an alloy of lead and antimony. Many common lead bullets have a copper or steel 'jacket' -Most accurate rifle bullets are a bronze-nickel steel mix, or a copper alloy.
The same metals used in long guns: A lead core with a copper jacket. Due to concerns about lead polluting the environment, some bullets now contain Bismuth or other metal.
I would like to know what the metal composition of bullets used during the Revolunionary War by the Americans?
This metal is lead.
Lead
The element Lead or Pb is used for lead-acid batteries, bullets, shots, but it is also a poisonous substance to animals!
In general, no. Lead is a very inexpensive metal. Custom bullets such as the pure copper bullets used in some hunting ammunition are made by a different process, and may cost more. On the other hand, there is training ammunition made with a plastic bullet for very short range target shooting- they may be a bit cheaper than lead.A new type of ammunition known as NT (for non-toxic) is now being sold. The primers contain no lead (most primers contain lead azide) and the bullets are either non-lead, or fully enclosed lead. These tend to be a bit pricy, but were created to address some of the health concerns with firing lead based ammunition on an indoor range.
