Congratulations for obtaining such a fine specimen. I think you will come to appreciate the workmanship of the Mauser factory very much. I too handload using 139 grain Hornadys; however, I have used factory ammo to great success. I have absolutely no complaints about Federal or Remington factory ammo as it performs quite well and is easily available in your area. It will do well on Texas Whitetails or Feral Hogs.

Good hunting.
