I have a Mexican small ring Mauser that my dad built with a new 20" Douglas barrel, really nice wood, Timney trigger and new bolt handle. He chambered it in 7mm-08. Is it possible to re-chamber to the more classic 7x57 without needing a new barrel? I know both rounds are very close from a ballistic standpoint, and I already have a Sako 75 in 7mm-08,but it just seems that this rifle would have so much more "cool factor" in 7x57.

Thanks in advance.
