Lighted Nocks Changing Point of Impact

[JJD]

29.5 " Carbon x maxima hunter 350, with accunocks, 100 gr Striker broad heads.   Draw weight at 62 lbs
Chrono at just under 300fps.
 Nocturnal "S", shoots less than 1 inch low (average) at 30 yds

I was given a sample of the Accunock a few years ago.  Looks pretty neat, though the technology is older than one might think.  Seems a guy gave me a sample back around '93 or '94 with the same principle though I do not know what happened to him.  Guess it could have been the same guy.  I have yet to shoot an arrow with one.  I'm intrigued enough I might give them a thorough work up this off season since the new Carbon Express nocks are horrible!  And I am just about out of my Easton Micro Lite and Old clear CE.  Was thinking I might have to go back to shooting ACC's just so I could get the X-Nock.  Was that or make my own X-Unibushing for the Carbon Express shafts.

1" difference at 30 yards changing nocks and adding the extra weight.  That's not bad at all in my book   Do you know what you ended up in FOC?

Will measure out foc tomorrow.  Don't mean to get off subject, but the accunocks did get me another 2 to 3 fps over the carbon x nocks.  They are however, fragile. A few dozen shots and one part or another breaks.  Not sure they are worth it.  As mentioned the carbon x nocks leave some to be desired.

Ya know Rad, that most important thing is that they'd look cool if I ever got to shoot something, LOL.

nocturnals fly great for me no change out to 70 yards

It's really cool when you miss   I did that on a buck up in BC.  He saw that lighted nock and walked over to it trying to figure out what that dang light was.  He was so confused by it he stuck around long enough for me to put one in the right spot

Maybe some Tinks #69 dabbed on the nock might help also.

Now you are talking   One day I will tell you a story about my evening with Tink and his daughter at the Houston Red Lobster.

Measured to tip if broad head
Accunocks Gave me 8.9 FOC
Nocturnals gave 7.8  FOC
1.1  difference
My understanding is that 7 FOC is pretty minimal.
Kinda surprised they were as close as they were.

My FOC with nocturnals puts me in the 10% range.

Rad, I'm just over 12% FOC with my Axis 300's and 125gr broadheads now. Putting on a Nockturnal would certainly change that but I really don't want to go to a 150gr broadhead. My total arrow weight now is 480grs and penetration is excellent. Accuracy is super based on our discussions earlier this year when I was trying to make 340's work. Speed is 270fps according to my Pro Chrono. Helical Blazers. Giving up some speed but accuracy and forgiveness is way more important to me.

Why not just add a slightly heavier insert and keep the broad head at 125gr?

This would work but besides adding a little bit more weight in the lighted nock and adding more weight in a heavier insert, I'd be slowing my arrow down more than I'd like to.
