Ok worked it a bit more tonight, going in a slightly different direction. Thinking back to when the arrow kept showing too weak of spine, and I kept taking weight off the tip, I went with the 180gr steel insert, and the 180gr field point.
This time, I cut an inch off the arrow (2018) and BINGO. Lined up perfectly, although still a little nock high. I suspected, so I checked, and 27″ was too short with a broadhead, so I went with 27 1/8, measured from bottom of nock to end of arrow shaft. That little bit keeps me from bottoming out on the riser. Oh yes, I did add a second nock set, as suggested. Didn’t change anything that I could tell.
Question, If It does turn out that I AM pulling the lower limb in, would changing to a higher (more straight wrist) wrist help this? Or would I be better served by just concentrating on NOT doing that?
I am starting to suspect that form MIGHT be my culprit on the nock high. I say might cause it’s a theory right now.
I am wondering if I might be pulling the lower limb towards me upon release, thus kicking the back of the shelf up and causing the nock to rise. Just a thought.
I am in the midst of getting the trailer ready for a trip Thursday, but when we get back, I might use the digital camera and video myself and see if that is the case.
Just for kicks, I put the heavy insert and heavy field point into a fletched arrow to see how it went. Now bear in mind, this is a bow I got off Ebay about 3 years ago and have never been consistent with it no matter what I tried. There isn’t anything PHYSICALLY wrong with the bow, I knew that, but I have never really tuned arrows to it either.
About 6 months back, I found that 2113’a flew very well, and once I chopped about 1.5″ off some cedar arrows, so did they. Hey, there might be something to this “matching the arrow to the bow” thing. 😉
Here also, I must confess that I read Dr. Ashby’s articles, at least some of them, and kinda felt like Ho Hum….not because they were boring or incorrect, they were neither, but because I lacked the energy or excitement, or the funds to take on another expensive chore of buying arrow and expensive heads for another inch or two of penetration. That was my impression.
Back to the fletched arrow, For the first time EVER since shooting this bow, I am able to hit where I am looking CONSISTENTLY. By that I mean that my field point target is a 24″ x 24″ x 24″ cardboard box, stuffed to near splitting point with plastic grocery bags. This has lasted me years. I have to swap boxes every now and then, but just reuse the bags. I have 5 bullseyes spray painted on each of 4 sides. EVERY time I moved to a different bullseye, I hit it. This is 10yds mind you, so nothing to write home about, BUT, the consistency is HUGE.
In addition, I get to use the heavy field point AND insert, for a real high EFOC (I know this isn’t in the FOC section), just mentioning that I did notice that the heavy FOC setup penetrates twice as deep as my std setup. That’s 6″ compared to 12″. I noticed the same when trying broadheads into my foam target, so I am please to finally match my heavy weights to the right arrow spine.
We get back home Monday, so sometime after that I will do the video and see if I can find why the nock is going high.
