In my humble opinion, if you've got a hunt in 3 months & your compound isn't an option but yourself a stick-on rest & a pin sight for your recurve/longbow. The rest makes arrow selection a lot easier & a sight pin takes a lot of the guesswork out. Don't believe for a second that you're any 'less-trad' because you use a sight & rest. If you were determined to shoot barebow, off the shelf then honestly, I'd say that 3 months is no where near enough time to gain sufficient ability to shoot at live game at much past 8-10yds.
Blind shootng is simply that. Stand abot 8 FEET from a bale/target set at about4' off the floor, nock an arrow, 'aim' at your spot & raise your bow to shoot, fingers on the string. Now close your eyes, draw the bow & shoot. It's not an instant thing, but after 2-3 dozen arrows you'll begin to feel what your body's doing as you draw, release & follow through. It's a HUGE advantage if you cen film yourself whilst you're doing this.
The reason that this works, is that your brain interprets visual stimuli far better than any of your other senses. If you can see your target, your brain automatically aims for the centre. If you miss, your brain tries to compensate & you'll adjust (subconsciously) your aim to hit the centre, rather than performing an identical shot. With your eyes removed from the equasion, you'll begin to feel differences between shots (ie; if you short draw/over-draw, drop your bow arm, lose back tension, collapse at release etc...) & your bodywill automatically try to make every shot feel the same. Once you've taken 3 dozen shots, your body will begin to come alive! It makes you aware of things that you'd never notice in a million years with your eyes open!
If you can video yourself, once you've completed the blind-shooting turn off the camera & put it away DON'T LOOK AT IT AT ALL!!! Repeat the excercise four or five time over a week or so & then watch all the video together. You'll almost instantly begin to visually relate to the feelings your body was giving you.
You may aso wantto check out Terry Green's 'Form Clock' at the top of this forum. Terry has (in my opinion) 'perfect' form. However, you should understand that not everyone can achieve this.
My old archery coach (UK Olympic coach) once told me that your form is just that; YOUR form. As long as you make every shot identical (Form-wise) then how you do it doesn't matter. Form issues are only issues if they are either unpredictable, or unrepeatable. If you consistently do the same things every single shot then don't worry about it.
Just out of interest, could you please tell us a few more details about yourself & your bow?
What are the specs on your bow? (length, weight etc...)
What is your drawlength & how was it measured?
Do you have arrows spined for your bow yet & how did you achieve this?
What is your previous bow-shooting experience with a compound?
Could you give us your height & build?
Sorry to pry, but all these bits of info could help us to help you improve safely & quickly.
Oh, and welcome to the forum man! :D
