Shooting base bow is all about form, form, FORM!!!
I shot competitively and hunted for years with fixed pins and fingers...so I already had the finger shooting part down pretty good. In January I took up shooting a stick to make archery fun again...it had turned into work with all the comp's. I've worked up to being about to easily hit a half gallon jug at 25yards.
Learn your form and after that it's just hand/eye coordination. A good way to do this is stand FEET from the target and shoot with your eyes closed...concentrate on hand placement on the grip, then feel the string on your fingers, smooth draw, hit your anchor point, release and follow through. You'll never feel most of this with your eyes open.
