csmith,
I suspect those cross hatch marks are remnants of the deep hole drilling that didn't get polished/lapped out. perhaps a chip got caught in the deep hole drill and scored the barrel. I've seen far rougher looking barrel shoot well, so, in my limited experience, I'd look somewhere else if accuracy isn't what you want, though the barrel is certainly one of the first places to look into. Have you sent these photos to Krieger and asked them about it? If they think it's their problem they might do something about it.
