"well, that's sorta true. faster rounds shoot flatter, and have less holdover at extended ranges, meaning their point blank is farther away, which means it's easier to hit something just by aiming at it."
But that's not accuracy, Andrew.
You can certainly hit your target more easily because you have a much greater point-blank-range, but that says NOTHING about the rifle's or the round's inherent accuracy potential.
If faster were TRULY more accurate, the .220 Swift would be the most accuract rifle round ever produced, the .45-70 would be one of the least accurate.
Yet both are capable of turning in groups well under 1".
