Zak,

Do you have a 3-d target? For $60-$80 you can pick up a cheap 3-d deer and I think you'll find this a hugh help before the season. The vitals of a 3-d deer are replaceable so you can see the outline of what you want to hit.

I find shooting at a target and a deer or 3-d to be quite diffrent. On a target a bullseye is very obvious(3 or 4 rings) where as on a deer it's not(all brown target). Shooting at a 3-d target espically in low light has helped my hunting a lot. If you shoot a 3 or 4 ring target in low light you can see rings. If you shoot a 3-d in low light you get a brown target with shadows. To me it is definately diffrent. Practicing realistic situations like a quartering toward or away shots are good practice. As others can attest a 3-d target should help you get ready for the season.
