If you want bowhunt, then the first thing you need to do is to learn how to properly shoot a bow.
The foundation of shooting ANY bow is the aim/draw/anchor/release/followthrough sequence, of which there are no shortcuts or gizmos that you can substitute with. These are all steps which must me learned by THOUSANDS of repetitions so that they become ingrained in your muscle memory.
One of the worst ways to attempt this learning process is by being overbowed. If the first thing that enters your mind when you draw your bow is the draw weight(because you cannot help but notice it), then you're overbowed, and the learning curve will be all that much longer, and you very well also learn some bad habits or develop form flaws because you are compensating for the excessive draw weight.
Ever see an archer point their bow towards the sky, like they are making an offering to the bow gods when they draw? Guess what, I'll bet that the vast majority of them are overbowed.
A compound bow (OR stickbow) with a max peak draw weight of 55 to 60 pounds is MORE than adequate for any whitetail deer that walks the planet, provided that you can hit what you're aiming at, you know WHERE to put that arrow, and you use SHARP broadheads. In fact, this will more than likely shoot THROUGH any deer you hunt at reasonable ranges.
As long as you have a 40# bow, why don't you use it to LEARN how to shoot a bow, and then move up 10 pounds to a heavier hunting bow. I can assure you that you're learning curve will be shorter, and you will have a MUCH more enjoyable time of it as you will be more accurate.
It's July right now. Even if you shoot 4 or 5 times a week for 20 minutes, you'd still be pushing it to think about hunting with a bow in 2 months (remember what I said about thousands of repetitions?). And if you did, you should DEFINATELY limit yourself to shots of 12 yards or less, which even a 40# bow can handle as long as you know where to place the arrow.
Take your time, do it right, and ENJOY THE JOURNEY!
