As most of you guys know I've been looking for a flintlock. I found a TC Renegade 1:48 .50 cal 27" barrel Flintlock for $310. From the pics it looks really good. Some handling marks but nothing major. Is the price right and would it be a good first flintlock rifle? Also is there a way down the road to change the barrel to a .54 cal and 1:70 twist? I looked on Green Mountain but it only listed a percus. I really want a flintlock, but I just dont want to blow money on something that I'm not going to like. Is the twist of 1:48 going to get me accuracy. I've heard that the twist isn't great for cronicals nor round balls. Is that true? Thanks Guys.
