I own lots of firearms, but not a firearms expert. I know the .257 Roberts is derived from the 7x57. I have an old custom 7 mm mauser that I have no use for, but am looking at getting a .257 Roberts, can this mauser be rebored into a .257 and what would it take. I know lots of you guys out there are very knowledgable, appreciate any input.
