I think the # is 4,380K - yeah, it's low. I was told this was the second set of barrels for this gun, as the first set diverged 12" at 100 yards, and shot at 10 o'clock, 4 o'clock by another 12". The owner said he returned it to Pedersoli, who 're-regulated the barrels" - which is unlikely. If they did anything at all, they merely put on a different barrel set and returned it.

I kinda wished they'd used a smooth reamer after boring the barrels. The bores are disgustingly rough, yet don't foul, so I can put up with it.
