I found it to have cold hammer forged...hope that helps. Happy shootin!

William, "Cold Hammer Forged" Sir. Winchester added a forged steel receiver that includes an integral recoil lug and a cold hammer forged steel barrel. With a bedded receiver solidly mounted to a free float barrel, the model 70 is built to be one of the most accurate rifles in the world.
