Rebored rifle and travel

[curtism1234]

I am thinking about having JES rebore a 30-06 to 9.3x62. They will scratch out the 30-06 in some manner (not sure if they essentially erase it or draw a single line through it still being able to see the original) and stamp the new chambering.

Is there a potential issue upon entering SA or Namibia? Let's say the old cartridge mark is still visible but a line through it

Thanks

I can't answer that specific question but can make a recommendation. I have a 450 Marlin built on a Ruger 77 short action and the barrel came from a #1 45/70 take off. The gunsmith put the barrel in the mill and ran a small endmill over the previous 45/70 marking and then stamped the 450 marlin in the same space.
You could request JES to do something similar.
