Nock Point Quandry

[joel0711]

Hatfield Take Down 50# @28"
I pull 28"
Arrows Gold Tip 600 (1535's) with 225 grain points
I have moved nock point from 1/4" to 3/4" but my bare shafts (enough duct tape on rear to simulate feather weight,I have a grain scale) but all my bare shafts are hitting low at 10 and 20 yards. I'm not the best shot around but whether my groups are real good or spread a little my bare shafts are still low. Should I keep slowly going up or down??????? Arrows flying ok, no fishtailing,etc

[Outwest]

I am not sure about the up or down but I would say that your arrows are to weak for your setup.

[McDave]

Yes, 50# @ 28” w/225 grains up front would require something like 400 spine shafts.

[Modad2010]

Are you shooting 3 under or split? If 3 under - are you using 2 nocking points? If you're shooting 3 under and only 1 nock point, you could be pinching the arrow on release.

What McDave said.

Try a fletched arrow and see how it flies.

[Rob DiStefano]

between the bow's holding weight at yer draw length, and the dynamic spine of the bare arrow shaft that flies well and lands reasonably straight in a bi-directional butt, the movable arrow nocking point will address "porpoising" (up/down). 

"fishtailing" (left/right) is about the arrow's dynamic spine and what amount of arrow paradox is required to clear the shelf, as directed by arrow shelf's pressure point location with regards its distance from the bow's centerline.

it's good to have a number of varied spine weight bare shafts that are cut to your arrrow and draw length, and screw-in point weights on hand for arrow shaft selection.  most stick bows will be limited in their built-in pressure point (that can't be moved, or moved very little), so between the shooter's inherent unique variables (consistent draw length, good release), and the arrow's dynamic spine, one spine range shaft and one point weight will yield good arrow flight and butt strike at 5 yards, and then 10 yards, quite well.  literally, it will fly almost as if it was fletched.

then tune out porpoising, if any, with a string nock point up/down adjustment.

Sounds like a three under shooter with only one nock point... There has been situations where split finger shooters would benefit from the second nock point as well.
Try different spines, but I would recommend a 500 spine unless your shooting full length. At full length, a 400 may work.
225 g up front is not really that much for a 50 lb bow shooting carbon.

I have shot a Bob Lee Recurve 62"51@28 and two Pronghorn Longbows 62" 51and 52@28 with a Axis 500 29" with a 75gr brass insert and a 175gr point or broadheads 3 under with no problem's

[hitman]

Yes 600 spine is too weak. Be way overboard to try to beef them up on front weight. Go to another shaft.

[bigbadjon]

I was a little confused by your problem? Are the arrows impacting nock low? Or are they hitting below the anticipated target?

That is my arrow recipe for most of my bows at that weight.

1/8 in nock point with 600's( 29inches) and 200 grain up front hitting together fletched and baree shaft. Nock seems low but it's working,raised bare fletch couple inches and no porpoising,etc
