Hey all,
Got an odd occurrence the other day with my new rifle. Its an Accuracy International Arctic Warfare in 308. Currently shooting 168gr Federal BTHP.
Back in August I zeroed it at 100 yards with a warm bore in 90 degree temperatures.
Yesterday I go to take a cold bore shot in 60 degree temperature. My cold bore shot is dead on at 100 yards. No issues.
But any shot following that was off 2 MOA high left consistently. Adjusted and came down 2 minutes and right two minutes and im back to zero for the rest of the day. No issues following that.
Now I have heard of temperature affecting the cold bore shot. But have not heard of it affecting my follow-ups unless it was zeroed for a cold-bore shot.
The rifle is used. Previous owner has probably 2000+ rounds through it. Its department issued and everything has been inspected by armorers. The scope is tight and the rings have all been tightened to the appropriate specs.
It is stored in a safe in the trunk of my car. Its subjected to some slight bumping around. But nothing jarring enough to knock the zero off the scope or anything.
My questions are
1. How do I correct this?
2. What caused this?
I am relatively new to the precision rifle field. So be gentle haha.
