The Renegade is a solid no frills sidelock. I personally prefer the T/C Hawkens though. Both use the same lock and maybe trigger (double trigger). The Rene has a 1" bbl vs the 15/16" on the Hawken. But the Hawken bbl is a couple inches longer.
You think you like the Rene now with the factory bbl? You ought to try them with a Green Mountain Long Range Hunter with a 1:28 or a slow twist 1:70 for round ball. Then your Renes will give any inline a run for its money in the accuracy dept.
