Sam Fadala advises pulling the 190 grain bullet from 303 Savage cases to load into 30-30 cases. I've never done this since I own a sweet .308 that hits hard with factory 180's.
Sam backs up his reloading advise with documented stories. He cites examples of Indian tigers, Alaskan bears, and Canadian moose taken cleanly by hunters armed with 303 Savage rifles over 100 years ago. This moderate velocity bullet which is both long and heavy has a stellular reputation for deep penetration.
