Busta,
I bought one of those cappers at Gander Mountain this weekend. You were right. They work great with 25 ACP brass. I also bought two of the U-View Flex Loaders. These have three tubes set into the same bio-flex silicone rubber as the capper. The carrier part that the tubes fit into has four holes that 25 ACP brass fits into perfectly. The tubes hold three pellets and a saboted bullet. I use loose Triple 7 and it easily holds my 295 gr Powerbelt and 100 grains of powder. I'm all set for a rapid reload now! Thanks!
