I started out using a spiral notebook that had load information in it, but didn't have the target group included. I included notes to indicate if it was an acceptable group, exceptional, etc. and any information concerning kills with that load.
I graduated to using index cards and cut the groups out and paste them on the card. Load recipe on the front, notes on the back.
I keep my stuff in a 3 ring binder as well. I use targets off of 6mmBR.com that I print on 8.5 X 11 paper and then punch holes in them. Take them to the range, shoot them, put them in the binder. All of the relevant load information and other specs are listed on the target. I also use the 24hourcampfire targets.
