I use flexible plastic clips at the range. You have to be careful which ammo you use. If the cases aren't crimped on the projectiles properly then the recoil can cause them to become dislodged from the cases. I discovered this when the cylinder wouldn't rotate after the first shot. The projectiles had worked themselves forward out of the cases because there's no magazine to keep them contained. I had to reseat them with a stick so the cylinder would swing out.
