What is wrong with this picture Im getting 52 lbs of KE. Im shooting a 25 1/4 in arrow at 8.2 gpi. That only gives me a 327 grain arrow? how is everyone else shooting so many grains? My arrow and broadhead are 307 with about 20 grains for fletchings.The last time i chronographed my arrow it was 265 if the chrono was even correct that is. what is the problem? I have to be shooting faster than 265! is it common to lose 45 fps off ibo?? with such a light arrow? Im a 28.5 in draw with 63 lbs on a hoyt havoctec
