Arrow shooting to the right

(1/2) > >>

MushinMan97:
Hi All! First time posting here.

I just recently built my very first self bow out of osage, along with a self-nocked bare arrow shaft made of multiflora rose. When I was using the tillering string for a couple of shots to just see how things felt and flew, I was able to hit the target perfectly with the nock coming straight out.

I have since made a bowstring for said bow out of hemp dogbane. Which is where my problem has started. I decided to use the same bare arrow shaft, and every shot started flying hard to the right. Hitting about 18 inches from 10 yards away, but in a consistent spot.

Any thoughts on what's going on? Nothing else had changed besides the string.

Bow specs:
60" tip to tip
40lbs @ 28 inch draw (my draw length)
No arrow shelf

Arrow:
30 inches
320 grains
Unknown spine

Thanks all!

its gonna fly different if the brace height with your tillering string is different from your brace height with the new string.

spine matters, but without knowing if you are righty or lefty and whether you are shooting off your knuckle or thumb.....does it seem like the arrow is flexing a lot or a little when you shoot?

TSA made some nice explanations. search his posts at

welcome to the forum

MushinMan97:
Thanks for replying Willie

I hadn't thought about the brace height, and now that you mention it I remember noticing that my new string seemed to stretch some and the brace height was shorter. Maybe I'll have to shorten up my string some.

I am a righty, and Shoot off of my knuckle. To my bare eyes, and my father's, there was pretty minimal flex in the arrow when shot.

And thanks for the tip of checking out TSA's posts, there's definitely a lot of good information there!

Pat B:
Are you dealing with a matched set of arrows or just a single arrow?

do you have a tip or point you can add to see what changes?  there are a lot of variables to tweak, but knowing if the stiffness of the arrow is in the ballpark is the first thing I would try to find out.

Basically, shortening the arrow makes it "act" stiffer, and more tip weight makes it "act"  less stiff.

the pic in the link was more related to comparing field points to broadheads, and maybe not too applicable at this point.

a basic observation is also whether the arrow nock end is skewed right or left when the arrow is stuck in the target.  you can actually see the arrow fly "sideways" somewhat as you shoot.

feathers correct poor flight making tuning harder until you get close, but on the other hand bare shaft tuning can be aggravating because small differences in arrows, bows/brace height and shoothing form, all affect arrow flight.

i would  try to understand what differences in arrow stiffness does before trying to tweak too many thing at the same time or adding feathers.
