SNovaTac, I cna fully understand your concerns with people handling firearms when the range is hot But you should take into consideration what type they are using and what theyare doign with it
I my self do handle SOME of my firearms while the range is cold. it is mostly cleaning of my muzzleloaders I also load my magazines during the cold time
I do not have a break action pistol how ever as long as the action was in the wide open position and left on the bench I do not see an issue with him putting rounds in the chamber. That being said if the weapon was being waves around and pointed in the direction of people I would not being saying it but just sitting on the bench is another thing.
When the rules are written they are geared to the lowest skill leveal. What is safe for a skilled shooter may not be the same for a begener, When you see someone handling a fireare you have to see what they are doing and how skilled they are before you get to upset
muzzle loader or not. it still not recommended to handle guns while somebody is downrange. just giving a bad example.
