Yes I can use the search feature and I know this topic has been covered in the past, but I have a couple of questions that I haven't seen answered yet.
Recently I purchased a Savage F/TR in .308. I have about 100 rounds down the tube and noticed a significant POI shift as the barrel heats up. Depending on rate of fire (barrel temp) the POI is about 2 inches lower and 1 inch to left of a cold bore shot at 200 yards. This was noticed on a couple of different strings on different days. Both days the ambient temp was about 70 and I was shooting one round every 1 to 2 minutes, 15 to 20 rounds in a string.
I recognize that custom barrels are stress relieved and don't exhibit the same issue (at least to the same degree) but I'm not ready to swap out the barrel on a brand new gun.
So my questions are:
1) Will this POI shift be consistent throughout the life of the barrel? If not, will it get better or worse.
2) Is there anything that can be done to reduce the shift or should I learn to live with it?
Thanks in advance for your help.
