My bolt gun smith is a long range National Champ. He also is making barrels for hunters. I feel he is well qualified to have an opinion on these.
Last week I was talking to him about the possibility of taking an vintage rifle receiver and making it into a sporter.
He recommended that I get an Adams and Benett barrel primarly due to the cost.
He said for $20.00 he would lap the thing. He has lapped a number and has felt tight and loose spots, something you will not find on high dollar match barrels, but still, barrels he has fitted to customer actions have shot close to half a MOA, which is outstanding for a cheap barrel.
Basically he would not use these in competition against the worlds best, but in a hunting rifle, they are just fine.
You must understand to, that National Champions understands Average Joe hunter does not need and cannot possibly hold to a 1/4 MOA in a hunting situation. It is my considered opinion that a 2 MOA rifle is more than perfectly adequate for game hunting in the US. My lever actions are 4 MOA, and I would not hesitate to take one out, as long as I kept my shots to around 200 yards.
