I have played around with Re bored barrels and budget barrels for p. dogs, chucks, and short range coyotes(300 and less).
I think of it like this, out of 10 barrels, 6 will work to the accuracy standard for your application, with 4 being a pain in the arss, being rough inside requiring more cleaning, or inaccurate requiring more load development. It is an absolute disaster when you get a bad barrel, many trips to the rifle range with many dollars spent on components.
I have chambered my last cheap barrel due to 4 nightmares in the last few years with a couple of different makers. Also, you can get a bad top-drawer barrel that is rough as heck inside, so service after the sale is critical for me.
The two Shaw barrels I have had were good for short-range deer hunting, they are rougher than top drawer barrels, and a Sunen hone machine is not used on them to make sure the bore is uniform from front to back to the 0.0001. Everyone that I have known over the years who has used Shaw to chamber a barrel has had excellent results with 1" groups being about average.
What one guy calls a good barrel another calls a tomato stake.
Brux, Krieger, ABC, Hart, and Muller, are my barrel choices, and the Hell that I went through trying to get those bad barrels to shoot 1/2" groups is enough to make me appreciate the quality and anticipated groups that will be shot with the above barrels.
