I am contemplating getting a Zouave but have a question about the rifling, The ones that I am looking at (Chiappa Armi Sport) says the rifling is 1 in 1660 mm which equates to 1 in 65 if I am doing my math correct, I contacted the company because I want to shoot minnie balls because that is what they originally shot and the company says that is what they recommend to shoot out of them but am concerned because the rate of twist seems very slow for a minnie balls, what do you guys think, Thanks Todd
