I have one Bergara and it would not group. Sent it back to Bergara. They sent it back to me with a target ,38 group. Took it to the range and used the same ammo Bergara used and it thew rounds all over the target. Called Bergara and they said I could send it back, but they would not do anything since they said it would shoot.
Bergara's Guarente is worthless so now I have a great canoe paddle!
I have owned a number of Weatherby's, and all shot well with no problems.
This is just my experience. Take it for what it is worth.
I narrowed my choices down to the same two and decided on Bergara. I felt the action was smoother and liked the grip better. I'm still waiting for it to arrive.
