So I just purchased a Savage pre fit barrel from a reputable manufacturer from a supplier I will not disclose at this time. Upon headspacing this barrel I noticed some things didn't really seem to add up. This barrel is supposed to be chambered 300 wm and is marked such. Look at the cast I took of the chamber compared to a sized piece of brass. Is it just me or does the cast I took look as though this barrel is chambered in 300 weatherby.
