I was sitting here today making up new set of load cards for my reloads. How many people use them? For me these cards are a life saver. I am always tinkering with my loads trying to squeeze the last tenth of an inch or less out of them. I like to have the following information on them 1. Caliber 2. Bullet 3. Bullet weight 4. Powder 5. Powder charge 6. date loaded 7. OAL 8. Primer 9. Case 10. Weather condition (When shot) 11. amount loaded 12. Group size 13. velocity (From chronograph) I will print my load cards off on to perforated business card paper so they can fit nicely into my ammo boxes. Once I fill them all out I will take and staple them to my target and put them all in a specific book for that caliber. I like to use 1" or 1.5" 3 ring binders for each caliber i load for. I find that this allows me to a. brag about how good my gun shoots. and b. have a quick reference of what loads to use or not. I will load differently for winter time than I will for spring and summer. I got this from my grandfather and father who used small books to keep track of the loads each rifle liked best. My grandfather had a great set up his reloading bench was in the same room as his shooting bench he would load five and shoot them then check the target and make adjustments in the loads. My father still has all of his dads load books from the years.
