1. Take an ordinary paper grocery bag, and cut it lengthwise in two.
2. Cut along the bottom corners of each half.
3. You now have two silhouette sized (idpa) targets.
4. Make a stencil out of cardboard which has a pie plate sized 5 ring, and a 10-12" octagon 4 ring around it.
5. The head is 5, the circle is 5, the octagon is 4, everything else is 2.
6. Record your scores so you'll know if you improve or not.
7. Since it's life sized, you can shoot it as far as you can see it. Put a dot in the circle if you wanna do some scope work. It's consistent, repeatable, and realistic. Shoot it backwards to make yourself 'guess' center of mass.
8. Other than the magic marker to draw the stencil, you didn't spend a dime. Well, maybe for the ammo.... and the rifle....
