Back to the Loomis that I opened this thread about.

Barrels are marked 12 Bore, 15 Muzzle

12 Bore is .729" - .739" per rules of proof, correct?

If I am reading the chart that I found online correctly, 15 Bore is .677"

My question:
For the plug gauges, that would mean .677" to .687" is 15 bore. Correct?

IF I am recalling/understanding this correctly, the barrels are still at/near original dimensions.

Bores are .735" and both muzzles are .685"

EDIT: I may have this wrong. Math says this is .050" of choke. With my Skeets gauge I thought it was .040". Will check when I have the gun out again.

32" barrels with tight chokes. I haven't measure the stock dimensions, but they are very shootable.

Sporting clays anyone? cool

The barrels cleaned up quite nicely.
