Has anyone any experience with Argentine Mausers? My local shop has a sweet spoterized Mauser with the original stock but cut down. Has an awsome peep sight with a good bore. It's listed 7.65 Argentine, they only want $149 for it. Is the ammo scarce or gone? can it be re-barreled in a lighter or equal caliber? Just Currious if it's worth the investment for a non reloader.
