I experienced a similar problem over the last week as the op did. Funny thing is on my rifle the 3rd round was also always the flyer. I then removed bedding from below, sides and front of recoil lug. I also seated bullets slightly deeper and the rifle then grouped extremely well. Unfortunately I did not try one element at a time, but by changing the two elements I solved my problem.
