Here is a great practice target

This is what I use to zero at 100 Yds and then have fun with the four squares.

Try it also for the 25 Yd Challenge...just be aware that the squares are larger than an inch.:50:

Thanks for the target. I saved it and will print some off and gie it a try. Looks like it will be a good one!
