.299 to .300/.308 is what I would think you would want in a .308 rifle barrel.

That sounds like Marlin Microgrooving to me. Those lands should be measuring around .300", plus or minus a thou. That bullet is just being slid down the barrel with wreckless abandon. I'm surprised that thing even hits paper being a "smoothbore" and all...
If you think about it, those lands are only .001" high. Time to get a barrel replaced.
