As noted above "IF" one does not consider the shear stupidity of those who loaded dense smokeless with a bulk/black powder dipper etc which gave from a double to triple load then as noted more steel barrels have been recorded as bursting from internal flaws than have Damascus, thus if Damascus is "Unsafe at Any Sped" (pressure) then steel is more so. Best stick to Tiddlywinks or such, You have been Forewarned.
Personally I will stay with the shotgun & shoot either type barrel with appropriate ammunition.
