You can look up a chart for scale offset at different locations on the planet to account for differences in gravitational pull caused by the earth not being a perfect sphere.  We have load cells at work offset by 0.0079% or thereabouts.

If we have any here I can't say I've ever seen anything odd? If it affects one shot, wouldn't it affect all loads the same amount, or is it constantly fluctuating?
Or are you pulling my leg and I'm too dumb to know it?

I wonder what the affect of a full moon would be on your scales Vall.  By the way I am pulling your leg.  My low shots are from localized wind microbursts.

A set of calibration weights is a good thing to have on hand, especially with an electronic scale. I recently obtained a set of Lyman's weights. Playing with them on my 65 years old Redding balance beam showed it to be spot on. But only if I had my tongue in the right corner of my mouth. Left corner for you denizens of the southern hemisphere. It counteracts the Coriolis effect.

Scales? Phhht. I just eyeball my powder charges and dip with a rusty teaspoon. Money saved from not buying scales goes toward important stuff like mustache wax and whiskey.

My intro to handloading occurred when I was a young teenager at the local gun shop circa 1966. The shop owner had a tidy business selling reloads that he concocted. I became his slave labor which was ok by me because it provided me with the .22 ammo I was oh-so-desperate for at the time. The drill was: resize (mostly .30-06) and re-prime, dip the case in a big keg of Surplus 4831 and strike off the excess with a butter knife, crunch a bullet down on top of it (.30 generic 150 soft points), repeat until the customer's empties were all filled. Heck, we even loaded .30-30's the same way - trusting that one couldn't squeeze enough Surplus 4831 in any cartridge to cause issues. Business was brisk right before hunting season - "Go get yer empties reloaded at Red's gun shop, they shoot hard and really kill deer dead."

I been with my Ham Radio hobby since the early 70's tuning and fixing my gear and I found that this new fangled digital equipment as well as the old glowing tubes the accuracy is only as good as the person at the bench tuning them with that golden screw driver.
I put my trust in the old balance beam like the 10/10 RCBS or the old Lyman. 
I spend more time prepping brass and behind the rifle finding and developing my ability with the rifle for the best accuracy then weighing black powder LOL.
