Short answer: absolutely.
Being able to shoot the bow correctly/proficiently is further down the list of priorities in becoming a capable bowhunter. I missed my first 6 deer, hit 1 of my next 3 (the one in my profile pic, 3 yards), then hit 2 of my last 2. Why did I miss? It was not due to lack of proficiency, but rather because I overlooked other, more important aspects of bow hunting.
Knowing what I know now, here is what I would have prioritized if I could do it all over again:
1. Safety. Always walk with arrows in the quiver, practice basic tree stand safety, learn how to adjust your bow correctly, always use the correct arrows, trigger release safety, etc.
2. Learning what constitutes an ethical shot for the game you will be pursuing. For whitetails, this means broadside to 45 degrees quartering away, standing still to slow walk, double lung penetration, and animal unaware of my presence.
3. Use the correct tips. This is usually specific to the species you are hunting.
4. Practice in the conditions you will be hunting. Consider clothes you will be wearing, hunting from a blind or treestand or around vegetation/obstacles, shooting while seated or standing, etc.
5. Dial down the extremes. Hunt 10 lbs less than you are capable of pulling back, and take shots 10 yards closer than what you can hit during target practice. There are many reasons for this, and it is very important. This is probably the most ignored advice by beginners, and leads to the most botched shots and missed opportunities than anything else. Peer pressure makes wannable he-mans and robin hoods out of the best of us.
6. Ok, finally proficiency with the weapon you are using. This is easy. Let's say your very first time shooting the bow you can hit vital zone groups 90% of the time at 25 yards. Congratulations - you are now ready to take shots at your quarry of choice at 15 yards or less. Practice, coaching, and adjusting your equipment will extend your range. This doesn't make you more ready, it just lets you take further shots.
