I've never heard of anyone being unhappy with a Noveske barrel..
Allow me to be the first....
18" 308 barrel on a MA10 build. It was a 1.5-2.0 MOA $600 barrel. Hugely disappointed and will never buy another. Sold it after several hundred rounds of load development. Now I run a mixmaster 308 I built and a JP 308. Both shoot circles around the Noveske barrel.
Hopefully you sent it back so they could replace it? Even Krieger puts out a bad tube now and then. But you always give the manufacturer the option..
But Schneider or Lilja, I forget which, refused to replace an undertwisted tube for a buddy once.... ordered X twist, would not shoot heavy bullets, then checked twistt... was off and they refused IIRC< or at least they refused to pay for the smith work to get one off and the other one or such.
