The top of my list are Rock Creek, Kreiger, Brux and Bartlien, each is a little different but they are cut rifled and I see very little variation in bore diameters and they are to spec every barrel I see, lapping is excellent and when slugged they are nice the whole way. The bottom of my list is X-Caliber, Lilja and Broughton, while I've used them and they have shot, slugging them and seeing the lapping and bores that have tight spots or bores that follow the contouring or fluting just does not inspire confidence, the only barrel I have returned multiples of is X-Caliber. Hart and Benchmarks I'm OK with but I would rather have the first on the list. I have not seen anyone that I can count on for more speed or less, that lays with each bore.
