Here's another technique:

assuming you drop and weigh ten consecutive drops and know what the deviation is....lets say it's a total variance of 1/2 grain....(+/- 1/4 grain)....and you want to drop 70.5 grains.....

set the measure to drop 70-70.5 grains....such that the max drop is what you want and the minimum is 1/2 grain low.....

Then just load the ammo.....

I guarantee you that you'll never be able to tell the difference between those cartridges and the ones you weighed 100%.....and at three hundred yards....neither will anything you shoot!

I actually did this with the 22-250 for a prairie dog shoot and it worked just fine.....all the ammo was good to go!

Since then I've moved to the extent possible to ball powders which measure closer to +/- 1/10th grain
