What do you think of this?

I suspect it could happen with just one firing.

I've seen and examined unfired guns and there is absolutely no evidence on the standing breech of any kind of impact marks.

I know they were test fired and patterned at the factory and how they came from the factory with no impact marks is a mystery to me.

I know B.C. Kinsey. http://www.bckinsey.com/
I purchased a beautiful Parker VH 20 from him several years ago when he ran the Kansas City Cabela's Gun Library and in fact just bought a 2 barrel 28 gauge RBL yesterday. I find him to be knowledgeable, honest and a pleasure to deal with.. I would highly recommend him.
