Vertical stringing as barrel heats up
So, I finally found a Remington 700 BDL in 308 and got out to shoot it a little today. Once I got on paper, i would shoot 4 or 5 shot groups pretty rapidly, say in under a minute and a half. Noticed that first shot or 2 would be at poa, then they would jump up 3/4 to 1 inch on shots 3,4,5. Now I know this is perfectly reasonable from a sporter weight barrel and does not bother me at all, I was just wondering if free floating the barrel or bedding or both would eliminate some of this. I know that its unreasonable to expect poi not to shift as a thin barrel heats up, but i was just gonna get yalls opinion on what might help a little bit.
Here is some pictures of my groups. In the 6 shot group, i shot 5, walked down to the target and walked back and shot the 6th.
