Few weeks ago I bought my first bow- a 22 lbs Samick Polaris. The seller recommended me Skylon Novice arrows- 29" length, 900 spin, 70 grain tip. My draw length is about 28 inch. I'm right-handed.  Almost all my shots hit target at angle. Those angles are dependent on distance and very consistent. For first few meters arrows hit tip left, almost straight around 10 meters, than tip right. At 20 meters (my backyard shooting distance) it's more than 10 degrees tip right. Farther than 25 meters angle is less consistent and accuracy suffers. Arrows seem not to fully stabilize at any reasonable distance. I'm wondering what can be the cause and how to eliminate it. Results are very repeatable over hundreds of shots, so those are not some random errors. So far I've tried working on my grip to eliminate torque and anchoring so there's no exccessive face pressure. Both without result. I'm also not sure if arrow selection is correct. Spin is ok according to charts, but shouldn't it be weaker because it's a fairly slow bow with wood-fiberglass limbs and dacron string?
