Just a few ?s about carbon arrows. I decided to give carbon arrows a try. I shoot a Darton Lightning bow 30" draw length at 60# with a release. In the past I was shooting xx78/xx75 2315/2514 30" with 100 grain points no problems with paper tune nice holes. What I did purchased 2 brands PSE hunter 300 and easton excel 340. this is what charts called for. Just testing the waters had the arrows cut to 30". PSE have 4" duravanes and excels have new blazer vanes. As for paper tuning had to go from 100 grain points down to 85 grain to get good paper tune. These carbon arrows fly. Is this common to have to drop in point wieght with carbons, would it be wise to go to next stiffer spine to keep 100 grain points. Just concerned for hunting purposes in future. With these carbon arrows I fly through the target my xx78/xx75 had to shoot the target a while before had to worry about shooting through it.So much for shooting in my screen-room addition on my house, until I figure out a better backstop.LOL.
