- When you're not using a gun, keep it on the table with the action open and the muzzle pointed down range. For extra credit, stick a chamber flag in the action.
When the range is cold, don't go near the shooting table. Step several feet away so that people down range can see that you're not anywhere near your guns. You may know you're being safe, but others can't necessarily see that. Use the time to step away and socialize with other shooters or to work on your one-handed texting skills.
Don't carry around uncased guns. When moving guns to and from the firing line, uncase them there and re-case them before leaving the line. Other shooters tend to get nervous when folks are coming and going behind them waving guns around.
