Home Forums Hunting & Shooting Long Range Hunting Cold bore flyer?

I was shooting my 7RM M77 tang safety yesterday and got a single flyer every time when the barrel cooled down and from the initial cold bore shot. What the group basically looks like is a flyer about 1" to the left then a seven shot group that is about .8" outside to outside. After letting the barrel cool down for an hour and a half I fired another round and it went into the same hole 1" left where the first cold bore shot hit the target. Next shot went into the 7 shot group again. Same thing happend again with the next cold bore shot.

The barrel is 100% floated and action bedded. I am not an expert and would appreciate any info, as some might be more familiar with this issue?

Thanks
