well drew,

-tensile strength is generally unknown...

-if there is deep pitting, especially if in front of chambers, dont shoot it...

-low pressure loads only, should be used in pre ww2 guns...

-and to be really safe, dont shoot modern smokeless loads in any gun with twist steel barrels...

there seems to be a reluctance of those here to share their general guidelines when evaluating barrel safety...

thank you for the data from others, regarding barrel wall thicknesses, that you shared with us here...

but, without guidelines, what value are measurements?

my guidelines are 90/30...

what are your guidelines when evaluating the safety of shotgun barrels? anyone?
