Mystery Mauser barrel
Picked up a cheap project mauser this weekend. It has a mystery sporter barrel on it I may want to recover. It has no markings. Grooves calibered .303” diam but crown is rough so I think it’s actually .308”. However, .308, although it chambers, is tight and pushes the bullet into the casing when I try to chamber. Any suggestions on what this could be? I will cast it at some point but it’s not an option for me right now
