The CCI was only 70 cents more and it looked worth it. I have a set of derringers in 22 Mag - accuracy is not as much an issue as reliability for short range platforms.
Seen some YouTube videos of people making some long shots w derringers but I have not had that kind of luck. The Triggers do not promote accuracy. Spent some time on it once trying to pattern top barrel vs bottom barrel POI at different ranges.
I used to own a Ruger Single Six w 6.5" barrel. I consider the 22 Mag a bit light for the ideal trail gun but several FTF members have used them successfully on Mountain lion. Some calibers just get the job done better than they look on paper - IMHO.
