How do I figure K.E.
I don't know how fast my arrows are. I don't have acsess to a chronograph. I also don't have an arrow scale, so I'm not sure of the weight of my arrows. I shoot a reflex gamegetter with cam and a half. It has an IBO rating of 295. My draw length is 28 inches On my string I have a peep sight with tube, a set of bow jacks and a Loop. I have a Whisker biscuit arrow rest with the new B2 biscuit. My arrows are xx75 2315 with the tapered inserts, fletched with 3 four inch feathers. I also have the EZ crest wraps. I shoot 125 grain tips. I have been told I need at least 60 lbs of ke to shoot spit fires. What do you think?

How many pounds are you pulling?

Here is a rough estimate tool. Add your arrow weight and speed and click calculate

If your looking to find out k.e you first must wiegh your arrow and shoot it through a chrono. when you find that out use this formula.. velocity x velocity x wieght divided by 450436 this will accuratly give you your kinetic energy. and yes you definetly want at least 60 lbs of bow wieght for expandebles good luck skina.
