It means it was the most accurate load tested in the gun at the Nosler factory and that data may be 30 years old.

It has very little correlation with what may be the most accurate load in your gun.

When looking at the data above, I'm going to start with the powder which I have in my stock, has the most velocity potential and is close to 100% case fill. I'll try that powder with a load close to max and run tests with 3 or 4 seating depths to see which gives the best accuracy. After determining the best OAL, then I'll adjust the powder charge for velocity and accuracy.

Correct. I don’t have a ton of powder, bullets or testing time. So I chose Nosler most accurate loads to save time. My rifle is not finicky and as stated above. I have old eyes and I’m not a great shooter. 😁
