While hunting I'll usually set things up so 25-30 yards is about the furthest point to shoot.
But when I practice, my backyard only allows me about 25 yards to practice. So when I do 3D shoots I'll shoot at some to the longer distances just to practice the long shots.
For some reason I seem to be able to focus better shooting at 3D targets then bullseyes at equal distances.
If you can find 3D shoots in your area I highly recommend them. They'll build alot of confidence and help out with judging distances in the field. Check out
