MY experience w/30-30 MOSTLY involves a 10" TC pistol. Pointed bullets flat to 150 or so yds whereas the roundnose 150-165s took a serious nose dive after that, but note 1800-1900 fps, was an avg speed for the short bbl. I'd use a RIFLE w/roundnose to 200 or so, not alot more, but if you single loaded spitzers, it changes things alot, 250 may not be a bad window for range in a rifle.
Just remember do not put pointed bullets in the tube...
