I agree, and have seen the same thing. The important part to remember, as posted several times by different guys is that no matter how it looks don't loose sight of the ball. That is to say, if it shoots like it is supposed to but looks really bad then roll on.
I have a Kimber Mountain Ascent in 280AI that I bought for hunting in the mountains. The chamber was so bad that it had to be set back and rechambered just to get the rifle to reliably extract!!!! Kimber was using Douglas barrels at one time {no proof here, just what I have read and been told numerous times}. They got into making their own barrels within the last few years and they are cut rifled. It appears that they also went with a Sunnen hone too. The top flats of the lands in this barrel are perfect and the bore does not copper at all. The grooves look atrocious and if there is a way to cut a more rough pitiful looking groove in a barrel I don't know how...cutting torch maybe, chain saw?? The point to all this is that the rifle always puts the first cold bore shot dead on dead nuts perfect zero. This being a "big game" hunting rifle, I have no complaints. I can shoot one shot and let the rifle set and completely cool off, shoot another and no matter how many times I do this they just about go into the same hole. But, sit down at the bench and try to see how good a group it will shoot in the typical way, shooting one after another until it gets hot and I am lucky to shoot a 2 1/2" group. I have to say, I was very frustrated with this rifle when I first got it and sighted it in. Then one of my hunting buddies pointed out, "you know, it does put the round that counts right where it needs to go everytime!!"
Bore scopes are a very useful tool, just don't dismiss a rifle for the way the bore looks until you shoot it the way it is intended to be shot.
