Title: nocks a little right
Post by: kirkwhitehead on July 11, 2007, 01:50:00 PM: 4560 cx arrows,29"bop 160 gr. fld pts. 48# @28"

I draw all 28"

my feathered shaft hits dead on and my bare shaft hits the same spot but the nock is leaning to the right about 2.5". the lower in pt. wieght the worse it gets. don't have any 200gr. pts.

do I need to get a bare shaft perfect or just close the perfect?
thanks

visit www.bowmaker.net (http://www.bowmaker.net) for a great tuning guide.

Personally, I don't pay attention to nock orientation in the target b/c the target material determines that just as much (if not more) than the tuning.

Fletch a few up and put some broadheads on. If those are grouping with your fieldpoints out to whatever limit you can shoot you're good to go.

Post by: kirkwhitehead on July 12, 2007, 09:14:00 AM: The only thing about the inserts is that I am already about 11gr/ lbs.

I do not want a 700 gr arrow for a 48# bow.

also as I went back more the bare shaft does go left.several inches. so it is stiff.
but the feathered shafts fly great.

Put broadheads on a few arrows and see if they'll group with the fieldpoints at your maximum shooting distance. If they do, then you're tuning is close enough. If they don't (and I'm guessing they won't) then you'll need to add more weight up front or go with longer arrows. Broadheads will magnify any tuning problems just like bareshafts.

I'm shooting 31-1/2" CE 150's w/125gr points from my 45# ACS-CX. They fly like darts.

Post by: kirkwhitehead on July 13, 2007, 08:24:00 PM: i went to 100gr inserts and 200 gr pts and still too stiff on those 4560's. might stick w/ my 1916's.
