For most pistol cartridges when loading in the middle of the range for plinking ammo a .2 gr variance is nothing to worry about.

Just for an example let's say your target charge is 5.0 gr. a .2 grain variance is only 4% off the expected charge weight. Not enough to notice or worry about.

If you are working with very small charges/ small cases, or max loads then it can be enough to cause pressure issues, but for middle of the road loads it is not an issue.
