not leaving brass around is another great reason..
Having one passed down through the generations is another good reason.
I like to clean up after I'm done with the range, and being able to put the collected brass straight into the container is nice.
I have several wheelguns in my collection, from single-action to double, and enjoy shooting them a lot.
Years ago I, I was advised by an old timer from back in the bad old days of real law enforcement that a revolver was a very good thing to have. Always ready and it goes bang most every time you pull the trigger. If it does not go bang, just pull the trigger again. A nice feature to have when the chips are down.
