I'm thinking it may have a trajectory similar to a softball at much over 25 yds. I use right at 600 gr. out of all of my bows, re-curve or hi-bred LB's. My bows range in weight from 50-65#. I use 160 grizly with what ever wt. steel insert it takes for my 5575 gold tips to just break 600 gr. Fly great for me.Gene
