Good call! If you do not mind the headstamp and fire-forming, you actually have plenty of brass options esp. now that Peterson makes basic belted brass, https://www.grafs.com/retail/catalog/product/productId/88972I appreciate all the suggestions, got way more response then I expected, my conclusion is to keep the STW alive!!
was able to snag some brass also found some brass in the drawer I forgot about, should be set for a few years if we use it just for hunting, leave the steel slapping for another rifle.. thanks to everyone that chimed in!
