To keep things seperated, I dump them into different plastic Folgers coffee cans that have avery stickers on them that say something like "300 WSM
-Norma FIII" and "300 WSM-Norma FIIII"
Then once I load, I'll have a note in the load box on a sticker noting bullet, base-ogive, cartridge OAL with comparator, powder, grains, primer, brass weight set, FIII
This stuff then gets transferred near the group on the target, as does any condition information and MOA for yardage info. Then the target group gets cut out and eventually taped to an 8.5x11 backer beside other similar tests, and slid into a page protector in a book.
When I go to dump the empties into the coffe can I look at the F number in the box and put them into the next one.
Another thing I do is always use the same case for my first fouler shot. On its side are sharpie hash marks noting how many times it has been fired. It is my benchmark of how many firings I should get out of my brass. Even though I may have 100 cases, that one gets shot with each set of 18-20 during testing. Twice through the brass and I roughly know how many firings to expect out of the brass. I religiously measure thinning near the base, and note the tightness of the primer pocket.
