I use a lot of Avery sticky labels. They have a 2x4" model (#5163 or 8463) that's ideal for load data or scope dope. Lately, I found an even cheaper source for the same label.

I use Labels Unlimited software, but Word, Word Perfect, Ultimate Label Maker, My Advanced Label Designed and LabelPro packages also work fine. You might even be able to fins freeware or shareware at download sites like
