Do they use Stainless or chrome moly? Also what process do they use to rifle the barrels? Hammer forge or button? I have found a few places to read about the subject but dont know how reliable the info is. One place said all of the big name companys like remington, winchester, ect.... hammer forge and savage is the only company that button rifles.
