? for heavy arrow shooters

[Anvil]

How far above center are you placing your string nock for shooting 750gr+ arrows?
Thanks

[Charlie Lamb]

Anvil... I could be wrong, but I see know reason that arrow weight would affect nocking point height.

Usually when I've found "the spot" for my nocking point on a particular bow, it stays the same for any arrow I might chose to shoot from that bow regardless of arrow weight.

[Littlefeather]

What about nock thickness on the arrow in relation to nocking point on the string? The reason I bring this up is if a guy is shooting woodies with fat nocks and also shoots thin carbons with very thin nocks. Does the nocking point on the string remain the same for both arrows?     :D     Tuesdays trick question! CK

[Roy Stroh]

Anvil I have found that the nocking point stays the same.

[Anvil]

Maybe I am not considering something else, but when I switch from say a 600gr arrow to a 750gr+ arrow, they come off the bow nock low. I know there are many factors that could cause this, but it seems that if I nock the heavy arrow above my nock set rather than below like I normally do, the heavies fly a lot better. I'll experiment some more this evening.
Thanks

For me the nocking point changes pretty much with the diameter of the shaft-it is really the location of the arrow nock as CK implied     . Woods, even tapered ones seem to want a higher point than carbon, arrow weight plays no role by itself that I have observed-750 grains nocks at the same place as 500. Typically my nock point ends up at 3/4 above center for woodies and  less for carbons.

Anvil:
Its the diameter of the shaft that effects the nock point placement, really nothing else. Remember the bottom of the shaft sits on the shelf or rest and the top of the shaft against the nock point(if you nock under the nock point) so the size of the shaft will effect the angle of the shaft to the string.

I don't think it has anything to do with the nock. Yes the nocks on carbons are smaller but so it the diameter of the shaft. Build out on the shelf may need to change. My guess is the stiffer shaft (carbon) isn't flexing enough to let the feathers clear the shelf so you might need to raise the nock point for that reason alone. The nock point for a wooded arrow may need to change if one used self nocks and didn't taper them making the nocks edge and the shafts edge be at the same point. Also tapered arrow shafts if nocked in the same maner would point your arrow skyward. Again, this would be more about the shaft rather than the nock.

[Anvil]

Good info guys! I shoot Classic nocks on all my arrows. My heavies are tapered laminated birch(750gr), my lighter ones are tapered sitka spruce(540gr)and 2020 Legacy's(610gr).
I am going to try some 160gr points on the lam birch and see if that straightens them up. I also tied on a nock point below the arrow. So with two string nocks, nock slippage should be eliminated.

I have had to move the nock point on one of my bows when using a heavy, high FOC carbons.  I assume it's because the spine changed a bit with the heavy points.

[Molson]

I have never had to change my nock point based only on arrow weight.  You have changed both the type of wood and the weight. Maybe that combo combined with your particular bow and shooting style just requires a nock change.  Could be a variety of things.

Have you shot several different birch shafts with the same results?  If not, it may be just a bad shaft or two.

[longbowman]

I shoot arrows from 450 gr. cedars to 850 gr. Laminated birch from the exact same set up and have had no problem with nock placement.  I'm interseted as to what you come up with here.

[Rick McGowan]

I've tried all of the fat wood, aluminum and skinny carbon shafts and my nocking point still ends up at the same place. I am sure there is a small difference, but it is so small as to be not a concern. I DO see a difference with the high FOC arrows, its one reason I'n not a fan of that.

[Anvil]

Thanks for all the feedback. Once I glued some 160gr points on them, they straightened right out. Apologies for asking thie question before further experimentation. It must be that the laminated birch doesn't have grain run to consider when spineing them so the stiff spine was showing tail low rather than left/right.
Thanks again.

Anvil,

Your different nocking point with heavier arrows probably has more to do with the two arrows having different spine than where the nocking point is. The higher nock position is probably helping compensate for the different spine.

[Wudstix]

I shoot predominantly 5/16" nocks on tapered Cedar or tapered Ash.  When I swith to 2020 or 2215, or Beman 400 there does not seem to be a noticable difference in performance out to about forty yards.
