I guess with the pandemic, it is ok to waste time on scale accuracy. The thing I'd like to point out to new reloaders or those considering reloading is that these sort of things aren't necessary, unless your scale is unreliable in the first place, which rarely happens with name brand equipment and if one follows the manufacturer's recommendations. Powder measures which throw + or - .1 grain are good to go. For pistol loading, the most important factor is the condition of the base of the bullet. Bullseye pistol competitors are the most discerning group of pistol shooters and these parameters will, with an accurate gun, produce 10 shot groups at 50 yards which measure 3" and under. Getting sidetracked with minutia doesn't produce better groups, it just wastes time that could better be spent on reloading more ammo or working on improving individual skill with the gun.
