If you can shoot a 3 inch group at 30 yards you are capable of taking a deer at 30 yards. I know you're striving for perfection as you should but it takes time. I started shooting a bow almost 12 years ago. I have good days when it's necessary to shoot at diffrent targets to avoid ruining arrows and I have day2 that don't care to discuss. If you can consistantly shoot a 3" group @ 30yds you ready for the woods. If you keep shooting and practicing with good form you're groups will tighten with time.
Keep shooting and having fun, That's what it's all about
