My step father has a rossi 92. I instructed him to get that dvd and kit to modify the lever action so that it feeds smoother. Well, he did a great job with the modification and it does feed smoother, but not with the 357. Seems those rounds are.simply too long to be able to feed smoothly without having to baby the lever. Anybody have any suggestions to correct this? He was telling me that a friend of his said he needs to use "specialized ammo" if he wants the 357's to feed as smooth as the 38's....true?
