What type of ammo is prohibited in the State of Oklahoma? The law says that ammunition that is less than 60 percent lead in its core and has a fluorocarbon coating, that means that the jacket is extra thick and there is less lead in the core than legally permitted.

What does this do? It allows the bullet to attain velocities which would penetrate police body armor, and that is a big no-no in the State of Oklahoma. You can get two years in prison for the mere possession of prohibited ammunition. Under the self-defense act, you cannot use a .50 caliber pistol in the State of Oklahoma and conceal carry it.

Any of the lawful ammunition available, which would be all of the other ammunition, does not have any particular legal consequences for using. However, the prosecutor could always argue the state of mind of the user of the ammunition, the so-called “Rest In Peace” bullets or Glaser Safety Slugs or other self-defense ammunition that is either frangible or of particular high energy would have some impact on the prosecutor’s case.

I would be speculating to state that legal ammunition has any negative consequences to it. You could load some special ammunition, hand load it, to higher than normal specs, and the prosecutor could argue that such ammunition was more deadly than the run-of-the-mill legal. However, the truth of the matter is that all ammunition, if it’s legal in the State of Oklahoma, is legal and deadly. Therefore, the prosecutor uses other facts to make his case as to the mental state of the shooter.

Now then, does the caliber used make any difference in a criminal or civil case? The caliber could make a difference. However, as I said before, all ammunition that is legal is considered to be deadly, and the choice is really a free choice for the operator of the gun.
