I noted that Federal has started to market their version of the 1 3/4 " minishells. I have had good luck with the Aguilla brand. In fact, they are all I keep in my Shockwave for home defense. Has anyone had a chance to try the Federals? The Aguilla shells can be hard to come by and tend to be a little pricey. Plus, while I have no problem with their performance, they seem to shoot "dirty" and make cleaning the gun more of a chore.
