A commercial Oberndorf Mauser barreled action in original 10.7x68. Pix below. Contemplating converting to 404 Jeffery. Seeking detailed "how to" steps required for competent gunsmith to perform such conversion. Found some four decades ago, at the 'high end' Beinfeld Antique Arms Show in Las Vegas. Something of a 'time warp' commercial Oberndorf Mauser barreled action in 10.75x68 and looking just about brand new! 'IF' it is refinished, masterfully accomplished! The seller purporting it to be prepared for rechambering to 404 Jeffery. All original & matching but for the bottom metal assembly which is original Obie magnum mauser length. Such serialed to itself. He was selling it as "too many projects". Now, some four decades later & having done nothing with it, to do that conversion soon or sell under same excuse! This post isn't about selling. I'm just looking to get a handle on exactly what would needed for a proper quality conversion. Detailed instructions concerning all steps necessary from original chambering indicated to the Jeffery. A central question also any action rail modifications typically necessary.
Thanks for guidance! Happy Holidays & Be Safe! John
