I had a new rifle built by a local gunsmith and it will not group at all with any kind of ammo or different scopes. It is a Remington 700 action with a Lilja heavy barrel. The barrel came as a rifled blank and he throated and chambered it. He trued the action and when you close the bolt empty or with a round you can feel it drag. The barrel is free floated and doesn't touch anywhere. I have been fighting this rifle for two years and nothing seems to help. I have taken back to him three times and he can't seem to fix it he has had it back now for about 6 months and I've heard nothing from him. Any suggestions besides a new gunsmith? It is guaranteed and I already paid for it in full.
