RE: Bow set up
Well, yes, any bow can be shot with a release. The problem is your arrow flight will probably be terrible.Even if it's not terrible, the arrowwill be flying off at an angle from your line of sight. For aright handed shooter, that means the arrow will strike further and further left as distance increases.
To use a release successfully, the bow's sight window has to be cut beyond center so the arrow can be adjusted to be directly in line with the string. That bow is not cut past center. The arrow will be pointing off to the left of the string. Just right for shooting fingers, but not even close for using a release. With a fingers release, the bowstring will move outward as it goes around the fingers, putting the nock end of the arrow in line with the point.
Don't worry. All is not lost. There is nothing horrendously difficult about shooting a bow with your fingers. It just takes a bit more practice than it does with a release. Not a problem for someone who enjoys shooting a bow. A good fingers shooter will not shoot as accurately as a good release shooter, but the difference is slight. It's usually measured in fractions of an inch.
People usually run into trouble because they try to release the string. That's not how it's done. It's impossible to make a good release by trying tosnap your fingers open to get themout of the string's path. A good release is happens by doing nothing. You are already doing something, holding the string and pushing your elbow back to maintain back tension. When you're ready for the arrow to leave, you maintain that elbow push, but simply quit holding the string. Just relax your fingers, letting the string pushthose fingers out of the way and excape.
Forshooting fingers with sights, the best anchor is putting the index finger at the corner of your mouth.
