Hey guys just wanted to get some input from other bow hunters. I recently purchased a new bow and got all of my accessories and got it setup. I talked to a few pro shops guy, a few guys I work with who shoot the same brand name bow and checked 2 sites where you put in all of your info and it calculates what speeds you should be getting. Both web sites said I should be somewhere between 323 and 325 fps. I am only getting around 307 through the chrono. The bows IBO if 350 fps. I am shooting 29DL with 70 lb DW with a 390 grain arrow. I understand you lose speed for being over 350 arrow weight and under the 30 DL when talking about speed but I was curious if I should have lost that much speed with my setup and if not what could be causing the speed to be that much off. I had it tuned when I purchased it so everything should be spot on. Thanks for any help you guys can give me!
