Lloyd,
If you remove the barrels and look in the slot where the lug goes, there is a thin section (maybe .060-.080 thick) under the water table on each side. That is where my 12ga cracked. I have also heard of cracks at the watertable/breach face intersection. When I buy Flues guns, those are the places I look at closest.
Of all the Flues guns that I have had and looked at over the years, the 12ga was the only one I have personally seen with a crack. That 12 was rode hard and sustained trauma.
I passed on a nice 30" 20ga the other day. Still kicking myself. Guess ya can't do all the deals.
Hope that helps,
Bill
