I guess it's crazy hard for some of u peeps to wrap ur head around the fact that heavier arrow shoots flatter than a light arrow but at longer distances....shoot at 150yds, the lighter arrow slows down and looses momentum much faster so ur aim point would be higher up above the target...more mass and more momentum in a heavier projectile so "flatter" flight path...graduate sloping hill vs steep drop off of the lighter projectile.....however...it is kinda mute point at our hunting range...me also thinks if u wanted to shoot heavier arrows at longer distances u just need single pin slider, sharpie, and half a day and that issue goes away also.
150 yards doesn't really mean much in bow hunting!
I'm shooting 635gr arrows this year just to sample the Fairy Dust. I shoot a single pin and HAD TO use a sharpie to make my yardage marks because my new trajectory was waayyy beyond what the factory tapes went to.
With my normal arrows my site tape went out to 100 and I was able to do my own dope out to 120.
With my heavy weights I can only shoot out to 70 yards (unless I aim high) because my arrows won't clear the site housing...
