What is the pattern scatter like,From say 10 FT.to 30 Ft.Or even 30 to 50 FT.
And Maybe just having it re-blued would help it. After all isn't the metal heat treated hardened Armor steel?
Is there any way to Mick. out both barrel's to see if there is any difference between the two?
I really don't know. you had a good Question; Or maybe just shoot from one side until the ring is the same as the other side; LOL LOL Sorry I could not help any more. My 12 sure is fine I just Love it, You Know I didn't even know there was any difference in the sounds of the barrels; I am tone def;I would not even hear that one would sound any different from the other.
