AF,
I guess he finds out when he runs a brush thru the barrel and pulls it back toward the breech and one day the rifling is missing 8" out.
No doubt in some cases the signs don't show up as in the case I cited in one of my previous posts. No signs. The quality of the Sako AV action on the particular rifle (in my case) must have masked the signs.
There was no masking the barrel issue when it showed up. Good discussion. Heading over to the Orange County (Florida) Convention Center this morning. Exhibiting at the PRI (Performance Racing Industry Trade Show) Hope all have a blessed day today.

Dave
