What is the the most flat shooting cartridge yall can think of?

[Arken7mm]

Looking at that link

My 7STW is running 500fps faster than the ones in the link

I believe he averaged them out...
"The following table averages multiple loads for each cartridge and shows an average amount of drop at 500 yards and 1,000 yards for each cartridge."

The 30-378 Weatherby Mag is impressive for such a large bullet. I think that could be the ultimate 30 cal?
