RE: Bow Hunting Noob Question..
I agree with ijimmy on this one. One month is justnot enough time to practice right.Most deer won't stand broadside at exactly 20 yds for you to shoot.
Buy the bow now and start shooting and you'll be ready for the late season or mid Nov at the earliest. There's a lot more to it than hitting a target at 20 or even 30 yds. A deer will not have a bullseye on it either.
Sorry if that seems harsh but we have to think about the deer and the image that archery have.
