Looks like it's doing good for a new barrel.
You may have found a barrel that's not too picky about what it likes.

I was going to shoot a CVA inline I picked up a while backin a trade, but the temps just below freezing scared me off today. Actually, the old shelter I had put over the shooting bench got destroyed in a storm this winter and I didn't want to set on a wet (frozen) seat. [:@]I did go pick up some new #11 & musket caps today, so I did get something accomplished as far as muzzleloader shooting. [8D]
