Found a new in the box classic stainless 300 ultra mag today.... previous owner bought it and never shot it Sold it to me for what he paid for it (had the receipt in the box) I didn’t need it but it is interesting for sure. Made me wonder what other calibers were chambered for them ( I have a 270 weatherby mag and a pair of 375h&h mags ( one six digit and one 5 digit).
