heres the thing, good condition barrels have been proven to be able to take modern smokeless ammunition meeting standard saami pressure limits.
lots of talking heads say never use a damascus barrel for anything but decoration. yet theres a few custom gun makers making damascus barrels today.
and its very popular to use old damascus barrels to make muzzleloaders.
since modern saami loads are based on the original black powder loads, why the problem?
