Ahh, gotcha Jimro..... because that is essentially what I do, use the accuracy load on virgin brass then do my load workup on once fired or twice fired.
I find similar results as you kind of implied also, which is once it has been fire formed, the load doesn't really change much in successive reloads, but there will be significant difference between brand new brass and once fired.

About that significant difference..... maybe if you neck size only...I can see that. If, however, you are FL sizing, the sizing process returns the shell to factory dimensions. How different is it going to be? You will have a different load in the case, THAT may make it perform better.

PS I shoot from a factory crate of brass. When I am done, I pick the cases up, bag them in lots of 100 and sell them to other shooters. They are not buying it because it will shoot better... they are going to size it. They are buying it because it is cheap.

I size all new brass
For me not to requires too much trust
( I have worked in factories, and I learned that SH!! happens )
( I was not there when it was made, boxed, packaged, shipped,
put on the shelf or when the package was dropped, stepped on
or played with by those that handled it )

Problems I have found with new brass --
bent necks
NO flash hole
Off center flash hole
NO neck ( bottle neck case )
Made with 2 pieces of brass (not on purpose )
NO primer pocket
Never been formed ( still just a round disk )

Stage how these defects got though quality control
So when I size, do the primer pockets, do the flash holes,
trim and chamfer, I WILL find a defective case
