I used to fill out forms for each test/shot etc.
Got old and lazy.
I now record the details on the target and post them on the wall. One awl (too thick for a stick pin any more
). Each shot is numbered and marked w/MV.
After loads are developed and drop charts developed and confirmed, I log each shot at rocks or game listing all of the environmental details, range and results + notes/considerations for subsequent shot adjustments.
