I know you are snake bit on the Bergara, I purchased two in the B14 HMR, one in 7mm Rem Mag and the other in 6.5 Creed, the 7 Mag was accurate out of the box, easy to develop a load, the 6.5 Creed, I am having issues with the 140 Hybrid, I have some 130 VLD to try and some Hammer Bullets on the way, I think I can get it down to .50 MOA. If I cannot, I plan to have it re-barrelled with either a Bartlein, Brux, Krieger or Hart. I have not heard of any issues with Browning or Tikka, you have a lot of options at your finger tips, good luck on your search. The 7mag I have it down to .50 MOA, it is the Grandson rifle, the 6.5 with 140 Hybrid range from .945 to 1.65 MOA at 100yds.
