The way my d-loop and nocking points are, my lighted nock has no wiggle room when placed on the string. Despite that, I get good groups. I assume I do not need to worry about nock pinch if I am getting good groups, even though the nock has no room to move back and forth?
Why would you want the nock to have any wiggle room? It should fit snug, but not too snug as to be pinching it.
I like a little wiggle room. I see you have soft nocks tied in above and below. Could remove one. What is the axle to axle on your bow? Reason i ask is shorter ATA seem to get effected by this. Longer the ATA, less string angle to pinch. Sent from my SM-S901U using Tapatalk
I also served above and below my nock point, between my D-loop, to avoid the loop from slipping down and getting too tight against my nock. It worked well.
A good way to check if it's pinching once you're at full draw is to remove the tip from your arrow and then draw back slowly. See if the arrow lifts up off the rest. Have a helper there with you just in case it does jump off the rest! I know you probably know this but will say it anyway, of course do not shoot the arrow with no tip on it. If the arrow doesn't jump off the rest when you slowly draw with no tip on it, I'd run it. Messing with your nock sets will likely change both your sight POI and your broadhead tune. I will also say, cutting a nock set off the string, around the dloop no less, this close to season will up the Murphy's Law percentage of nicking the main string about 10x.
I always tie nock sets. After a shooting a while, it seems like my d loops start to squeeze down on the nock. While nock pinch sometimes doesn’t show up right away, it ends up becoming an issue for me. Also, when replacing a d loop, it makes it easier to know I’ve got the d loop in the same spot as before. When setting up a bow, I wait until I’m certain on d loop location before tying the nock sets. I’ve also tried to get away with just one on the bottom of the loop, and that didn’t pan out, so I always tie one above the bottom knot of the loop and one below the top knot.
