I have one dated 1929. I have no opinion on any particular date being the best. Since the 99 was capable of chambering much more powerful rounds with spritzer projectiles, I don't think the 30-30 was one of the more popular chamberings. However, if you are a handloader, this platform will allow you to squeeze out all of the potential of the 30-30 cartridge. I have a pretty respectable collection of 99's and have never really run into one that I felt was manufactured poorly. Even the later versions with detachable magazines are fabulous rifles.
