The idea seems to have some merit, but I wonder about the need to orient them in a particular direction, and about long-term ammo retention...

I tried em, because I was shooting a 7-shot 686+, and speeloader technology for that gun is rather spare. Unfortunately, I found them ridiculously sticky and slow; not suited to competition, and certainly not something I'd want to mess with in any realworld sit.
Too bad, cause they're cheap.

These were the only speedloaders I could find for a S&W PC 627 (8 shot). I tried them a couple of times, they are as ChristopherG described them. The rubber has a tendency to "grab" the cartridge, thereby slowing down the loading process. It worked with 38sp but the 357's were too long cuz the cyclinder release got in the way (don't know if same applies to any other revolver). Anybody wanna buy some minimally used ones?

Oleg:
Oooops. Forgot to add, you do need to orient them a certain way to load. You have to orient the speedloader in a particular direction, slip the cartridges into the cylinder, then with a "wiping" motion, push the speedloader away from the revolver cylinder and you've loaded it. I think I'm going to try moonclips next.
