I am interested in getting a pretty decent 99 in .300 savage. don't know much about them except I've always thought they were right up there in the cool gun category like the Winchester 1897 etc. I don't know what age gun I want but would like one with the round counter and factory drilled and tapped for a scope mount. these old eyes and bifocals don't do iron sights very well any more. I want a shooter grade gun that has not been abused. can you help with what years the above features were available? thanks in advance. lee
