You should technically be able to look at your aiming point, raise the bow and point it at the target, then draw the bow on the target. All this without ever taking your eyes off from the aiming point. It should all be nice an smooth without straining yourself.

I will give you a few tips for shooting more or longer. First of all shoot less arrows at a time. Try shooting three arrows, then going and gettting them instead of 5 or 6. Your out of luck if you shoot 5 spots though.

Another great tip is doing an aiming excercies. You pick a spot on the target then draw on it. After doing that you aim for a few seconds until you settle down. Then you let the bow back down. DO NOT fire an arrow, just aim, hold and let down. This is great practice for target panic, it helps you hold more steady and helps if you have trouble getting the pin on the spot. But more so it build up muscles quickly. With high let off bows it is actually a bit harder to let the bow down smoothly than it is to draw it.

You will get tired fast doing this, so go easy to begin with and take your time.

Oh, and pick a different spot for every shot.

Also practice drawing your bow from a stand. It makes a difference. I can't draw nearly as much weight when I hunt from a stand as I can target shooting off the ground in casual clothes.

And for non hunting stuff, who cares about draw weight. Especially for indoor stuff where the distances are known. I shoot indoors with 45 lbs sometimes. 3-d would probably want the extra poundage for increased speed though. Keep in mind you only gain about 2 fps per pound of draw weight. Turning your bow from 65 to 70 lbs may not even increase your speed enough to make a difference in trajectory in real life. However 5 lbs of draw weight might be enough "felt" draw weight to cause your form to suffer and make you shoot worse, especially after 10 targets or so.

Nothing in life is free.
