How does stability increase as a bullet travels down range? I have seen marginally stable bullets shoot well at short range and then start to show oblong holes at longer range.The SG will be higher farther out than it will be at 100 yards.

After 500 yards everything becomes difficult to repeat. I have a 30-06 that will put Remington Core locts into a sub Moa group at 400 yards. After that, I don't know where they hit!!!

So even though your getting sub groups at 400, your loads could be falling apart when you go farther.

This it a sporter weight factory barrel that is 40 years old?

So many factors go into longrange loads troubleshooting.

What exactly is your twist rate?
