When the availability of the CCI #41 gets a little better, they're definitely worth checking out.
One thing I like about them is that the harder cup material makes them not as "picky" when it comes to priming crimped brass. I barely have to swage the primer pocket, and the #41 will still seat just fine. In fact, before I knew better, I primed a bunch of previously-crimped brass with #41 without removing the crimp at all.
Also, the #41 is a different color than the CCI small pistol primers (gold-ish, rather than silver), so if I accidentally leave a few in my primer feeder, I don't get confused as to what they are.
