Calibrate mine every time. It's about as accurate as yours (+/- 0.2 grains) which is why I verify the loads when it comes to powder it doesn't meter well.
I don't just let it dump and then stuff it in the shell blindly...I adjust it however it needs to be. But since the straw trick I would say majority (85-90%) of the time it meters it dead-on, whereas before it was only metering around 10% dead-on.
It helped significantly.
