You can increase crossbow arrow speed by reducing total crossbow arrow weight, but only on crossbows that are not arrow weight sensitive, such as Barnett Crossbows. Each 5 grain reduction in arrow weight provides a speed increase of about 1 foot per second. Thus, if you reduce arrow weight by 100 grains, you increase speed by roughly 20 feet per second. By reducing arrow weight you effectively increase arrow speed which directly affects crossbow arrow drop at a given range.

 Just how profound can this arrow drop be, EXAMPLE; we'll say that you are shooting an 20 Inch Easton 2219 aluminum shaft with a 150 grain arrow point, velocity is 250 feet per second. You have been doing a lot of reading lately and you read that Easton has a new crossbow arrow out called the Easton Carbon PowerBolt and that they recommend a 100 grain arrow point for correct F.O.C., so you try them out. There is approximately 135 grain arrow weight difference, with the PowerBolt being lighter. The arrow drop difference between the 2 at 50 yards is 10 inches.
