I do. Works well. I have a column for the lot#, brass type, times shoot and last anneal. Power type and load, bullet, seating depth, range shot at. target distance, group size, velocity for each round, Average velocity for the group, ES, SD. Then have a notes column for wind, temp, other facts. I can print the columns and rows out on a single sheet of paper and it goes in the case with the bullets. Usually 20 rounds per case. I can them fill out the info at the range and put in the spreadsheet later for review. Kinda helps me when i have a lot of loads to review...
