For a flinter, I'd listen to Cayugad. I like my T/C Hawkens and Renegades (the older Renegade with double triggers). The Lyman Deerstalker and Lyman in general have reliable locks too. The only thing I'm not crazy about with the Deerstalker is the single trigger. It is just too heavy for my taste. I much prefer the "hair" trigger on the T/Cs once you pull the set trigger.
