Erratic arrow flight

[DapperDan]

So I've been shooting at 20 yards every day the past week or so working on form, accuracy, ect, and backed up to 30 today to start working on longer ranges and sight in my 30 yard pin. I seem to have an arrow that wants to fly erratic at 30 yards and haven't noticed it at 20 yards. They are brand new arrows, Easton axis cut for a 27.5 draw length. I have lighted knocks, 2 inch Blazers with a helical/offset and 100grain field tip. Shooting out of a Mathews no cam htx set at 70 lbs. 4 of my other arrows seem to group just fine without any erratic flight or not any that I can tell. This one seems to wobble around a lot during flight but still hits close to my other arrows.

Any suggestions???

Spin test.

Mark your arrows to be sure it's the one. You may want to nock tune that one to see if it flies better.

Number them with a paint pen and leave that arrow in the bow case when you head to the stand.

So I'm sure that it's the same arrow. Haven't numbered them yet but pull it and reshot it 3 times in a row and same result every time. Other than shooting 15 to 20 shots a day for the last week they are brand new. And I shoot at different bulls eyes on my target with each arrow as to not damage them.

If you mean make sure the knock is in line with the vertical fetching then it is. And it spins fine. I have 2 dozen arrows. All are the same arrow. I was going to practice with 6 and hunt with 6.

You may have to make sure the ends are square by using a arrow square, on both ends. Sometimes they get cut crocked...

You can spin test it, but I doubt that's it (runout). More likely it is an out of square end, either tip or nock end. Use and arrow squaring device and clean the ends up.

Some arrows just have to be culled.

Yes, that and turn the valley of the nock to the next vane and shoot it. If it doesn't fly better turn it to the next vane and shoot again.
