Wondering what everyone else is seeing on the speed of their Nexus (mines a 4)

# : 70
DL: 28
Arrow: Axis 340, 28.75" C to C
Insert: 50gn
FP: 125gn
Total arrow weight - 480gn
D-Loop
Peep
Chrono Speed - 264 (2 different chronos 12+ arrows)

Archers advantage estimate is like 290. I know the data out is only as good as data in, but just wondering what others have been seeing with similar set ups? Any other input appreciated.

How does your bow tune with that arrow configuration? Interested in the length and weight
Arrow flight looks good. And they group as accurate as I am. But I need to shoot them through paper again. I know according to the charts and Archers Advantage I'm underspined.

According to this calculator you should be around 275 at those specs, not sure where AA gets 290. Lots of factors to consider where you’re losing some of the speed- some fletching configurations are going to cause more drag than others, if you have the bow set to a higher letoff it will be slower, how perfect your tune is…I would bare shaft tune it to find the sweet spot where you’re going to maximize speed. But I think the biggest factor may be how severely underspined you are. That arrow is so weak that a lot of the bow’s energy is being lost in an arrow that’s flexing like a wet noodle.

Nexus 6 at 28" DL (on draw board) a hair over 60lbs. 345 grains TAW VTAC 25 300 spine cut 27" CTC with 100 grain points and AAE Max Pro vanes. Speed is between 284-286 FPS. Adjusted IBO (real world speed) is approximately 328 FPS from listed IBO of 331. So basically, the IBO speed listed by Prime is legitimate. My bareshaft tune is perfect at 20 yards.

Nexus 6
Peak weight 65.4 lbs
Holding weight 14.3 lbs
Draw length 29 9/16”
Arrow 510 grain Easton Axis Match Grade, 300 spine cut at 30” with 50 grain brass HIT insert, 100 grain points, 4-fletch Bohning Heat vanes, Beiter Hunter nocks

Hitting right on IBO speed or a touch over depending on which calculator I look at. I believe the N6 will be coming to the elk woods with me this year.
