I have tried everything on this thread except loading into the lands without success. My question is have you shot your load with ammo in the mag and tested runout and seating depth after a shot or two. I am worried seating into the lands or at the lands for hunting is not going to work for my gun as the bullet will not be seated deep enough to keep everything straight and consistent with recoil.
I have done some work with seating into the lands with the 6.5x284 and checking for alignment/condition of the rounds loaded in the magazine. Depending on your chamber, if a round that is loaded onto the lands has .1-.2" into the case the bullet will hold it's runout and not move on recoil. You may have to size the neck .01-.02 tighter than you would normally use with deeper seating though. If the bullet doesn't move when the loaded round is pressed against a wood bench you should be fine. The bigger issue is keeping the same rounds in the mag without rotating them. Even with a brake, the bullet tips will deform after a couple of firings with some rifles. A piece of electrical tape on the forward portion of the mag box helps.
As to the fliers. The Bergers are sensitive to seating and your gun may respond to seating into the lands. How many rounds do you shoot before cleaning? I have had a few rifles that need to be well seasoned before setting down. I just went through a situation similar to yours with a 260 Savage LRP. After 20 consecutive rounds down the pipe the fliers ceased and .25 MOA groups settled in with no fliers. I'm at 200+ rounds and they are still holding.
