I have a couple commercial mauser magazines, that have been giving me issues with being able to seat all but the lighter for caliber bullets out near the lands. I would like to get them lengthened to 3.6", I have made an action to work for one I had bought on ebay that had been extended. I do have a mill but my welding and fabricating skills are not near what they should be so I am looking for a smith who is familiar with job.
