When I was manufacturing furniture products a lady came into the the shop. She wanted some table legs. I picked some up and gave her the wholesale price. She said something like, "I don't think those will be good enough. The price is too low." I picked some out of another batch, which were exactly the same, and doubled the price. She said, with a smile, "I'll take them."
My daughter wanted to go hunting. I had a heavy barrel Savage at the time. I went on line and purchased a .25-06 barrel for $130. I had it installed and rechambered for .257 Weatherby. Once I developed a load I took it to the range everyday for six days and fired one shot at 100 yards. At the end of the six days I measured the group: 1 1/32". That is MOA from a really inexpensive barrel. By the way the velocity averaged 3,695 feet per second with Barnes 100 TTSX for those shots.
