I doubt you'll be using a data sheet for actual hunting except to record your sight settings for different ranges and ammo.
But for practice, you can make this one work. Just use the one inch squares to plot you hits and calls. You can use any distance that suits you.
Remember, THERE IS NO SUCH THING AS TOO MUCH DATA.
Pistol/Revolver shooting is a bit different then rifle shooting, but at the same time they are the same.
Each time you practice, plot the hits. Every now and then draw on the plotting sheet, from 12 to 6 and from 3 to 9. You'll have 4 quarters. On each sheet, count the number of hits in each quarter. It doesn't matter the size of the group, what matters in the hits in each quarter. If you don't have the same number of hits per quarter, your zero is off. Adjust accordingly.
Thats why Calling your shots is so critical. Be honest with your self, cheating on a data card will hurt you in the field.
Hope this helps.
