So in a nutshell you shot thrown loads and anally measured loads out to 800 or 900 and couldn’t tell the difference!That test however was done shooting prone using a sling'n'irons rifle , not a bench rested , scoped rifle .
It was actually my 500 meter scores and groups that lead me to thd test , but that was done at 800 not 500!
At 500 meters only 7 rounds in 95 were outside of 2MOA vertical ( the bull on a TR target is 2 MO, the V Bull is one MOA)
With thrown charges .
The test at 800 was done with thrown charges from a Harrel measure and weight charges from a V4 trickler and lab scale - the same rig used by the best high master Fclass shooters in the World.
The rounds were handed to me at random so I was not aware of which one I was shooting , and the results recorded.
The results basically told me that I would not shoot any better using the weighed charges as opposed to the thrown charges on the Harrel's measure .
HOWEVER, this was a real World test, with swirling and following winds using an irons rifle .
Others will undoubtedly be able to get better results with a good scoped rifle and an F/O style front rest and rear bag.
Attached is a 900 meter ten shot group from that test day that was shot afterwards
NOTE: The test was for group NOT score
The result of this and all my other testing was that the nut behind the bolt is the biggest variable .

How can that be? Everyone knows you have to measure to the nearest 1/1000th of a grain to get accuracy………..(sarcasm)
