I know that feeling. If you miss, your speed loader will drop all of your cartridges on the ground. While normally it is best to keep your hand on the fire control, a revolver disengages all chambers so you cant fire it when reloading anyways. I would use the non-firing hand to grasp and hold the bottom of the frame and the cylinder locked outward and feed the speedloader (or better yet, moon clip) in with the non-firing hand. A lot less embarrassing fumbles.
She seems to have replaced her bullets with those flat, short, cylindrical neodymium magnets, though.
Also, if that's a S&W 500, that's a heck of a snubnosing.
It looks like a full wadcutter cast bullet (boolit for you cast forum users). I like full wad cutters because you can cast them easily and they have pretty good terminal ballistics as is. They also don't use up too much case capacity so you can still retain a full velocity load.
