How do you keep track of your load data?

[kennedy]

I number each of my boxes i put my reloads in, then I use that number to referance back to a manual spread sheet which is a page for each cal. Once I shoot all the ammo in that box, i cross out the line on the spread sheet with a red pencil, but can still read the info. then I reuse the number. When I shoot the ammo, i use the same number of the box to mark my targets, so when I can get home I can transfer the target data to the spread sheet.
