I don't know what my speed is so I'm guessing 280 ft/sec. My bow is set at 65 lbs but maxes out at 70 lb's and the IBO speed is 330 ft/Sec. My question is how do I find out my speed without a chronograph and do I have enough power?

Thanks

Do I dare say it? Slide Hammer from New Age Archery Products lol! This is one of the things it was built for. It'll add the extra kinetic energy, force, momentum you seek. It has mass, it moves within the arrow so it has acceleration/velocity. It has almost no effect on arrow speed. Look at the formulas for kinetic energy, force, and definition of momentum there is all your proof.
