I have 4 30-30s and shoot nothing but 170s down all of them.
As far as store bought ammo goes, there is absolutely no advantage to 150 gr. bullets. The velocity figures have been "fudged" for years. Factory Win or Rem 150s only go about 50 fps faster than 170s. You have to handload for a noticeable velocity difference. Even then, I still like 170s best.....
