Very much appreciate the donation of a 16g Syracuse Arms Co. Twist barrel which sadly was likely the victim of an attempt to lengthen the forcing cones, and 16g short magnums
Both chambers still 2 9/16" but the MWT at the end of the right chamber is only .087; left was .110.
Note the No. 0 16g Smith had a MWT at 3" of .114 right and .120 left.
At 3 1/8" there are four 1/4"-3/8" bulges; at 2:00, 5:00, 8:00, and 10:00. The WT at 3" was .098 and I was able to get the pin in the 5:00 bulge and the WT was .093. On the surface, that bulge appears to have a crack
At 5 9/16" there also appears to be a surface crack. WT there was .050
So the barrels are unusable, except with sub-gauge tubes BUT will be perfect candidates for radiography to confirm the depth of the cracks and possibly section and photomicrograph the cracks and the bulges. Knowledge advances
Still waiting to hear from TEAM about the Smith No. 4 barrels. METL should have the failure analysis done this week.
