Saving this thread. Great info.
I just bought an old Sako / Westernfield L57 .243 win , that has 22" barrel with .568 OD at the muzzle. It's going to Jes for a .358 win rebore same as yours and then ceracoated.
That should be a good one.
Of course, expect photos when you get it done.
UPS or USPS both ways will take more time than JES.
Amazing turnaround, good price and great work...
