What's its purpose? Home defense or hunting??? For home defense I favor the .357/.38. More capacity in the tube, little recoil with quicker follow up shots. Plus it's a great sidekick to my revolver. They are rarer/more expensive than the 30-30.
If huntings the game then go with the 30-30, bigger is better.
