It seems like everyone is very concerned about getting their arrow weight super low to maximixe their velocity. The more that I read about how weight and FOC effect accuracy, the more that I'm convinced that a 150 grain broadhead is more accurate for a crossbow. Excalibur recommends a 150 grain broadhead for the most accuracy. They are OK with 100 grain, if you are OK with less accuracy.
What do you shoot?
