20 fps out of the same bow at 40 yards with the same poundage is a 1/2" difference on a 3 yard miss(only difference is arrow weight).PERIOD.I have done and proven it too many times.


You are comparing 2 bows with 2 different amounts of stored/potential energies,the differnce is the energy level,NOT the speed.

Theold bow probably has an ibo of around 320 and the new one is probably around 305.That is the difference you are seeing.
