Our board of directors at our local club has banned all coated bullets on the indoor range. We have a rule that no jacketed bullets or gas checks are allowed. Now a few guys have been caught shooting copper coated bullets so they have banned all coated bullets including Bayou Bullets etc. There are camera's in the range and they said with the different colors of coating they cannot tell by the recordings if they are copper coated or not. So now lead is all that is allowed. It has always been target velocity only as far as loads.
