Here's a short video of me doing reloading drills with my Smith & Wesson 625 JM and the excellent James Austin's Moon Clip Server for USPSA matches. First segment is at normal speed, 2nd is shot at 120 fps of a normal reload where you'd "guide" the bullets into the cylinder. The 3rd segment is a 120fps clip of the "throw" method where you'd literally toss the moonclip at the cylinder face and let the rounds drop in by itself. I wasn't too confident of that so i'd only throw it very close to the cylinder. Someone more experience would be able to throw it from a further distance.
If you're interested in getting the Moon Clip Server, send James an email at [email protected].
