You may find that plated bullets won't be allowed in a steel challenge match. Because you really cannot differentiate jacketed from plated with a visual inspection and most steel matches won't permit the use of jacketed ammo due to the potential for ricochet's and possible injuries.

What will work is the new polymer or powder coated bullets because a relatively soft plastic wont ricochet or cause injury. So pay attention to that recommendation for Bayou Bullets.
