Well, I'm going to throw in my 2 pennies worth on this discussion for you to consider. Mauser conversions on today's market can get very expensive and unless you have the services of a very good gunsmith you need to tread carefully. I tried the Mauser conversion route on .458 Win Mags and it gets expensive and something always seemed to not work out with them. Magazine box too short for certain rounds and feeding problems, magazine floor plate issues, and other minor items. Before you do that I advise that you carefully look at what CZ, Ruger, Winchester, Weatherby, and other companies are selling brand new in models specifically designed for .375, 9.3X62, or any other round. The simple fact is that you can buy a CZ very reasonably right now and take it to any competent gunsmith to have the action smoothed and the stock glassed... and end up with a very fine Mauser action rifle for probably less money than you'll end up spending on an old warhorse conversion. Been there, done that. The conversions are all gone at my house and I have a Savage, Ruger, and CZ that work much better than any of them did.
