[QUOTE="Twanger, post: 623822, member: 43393"] lightbulb The 100-yard data through the chrony published back on page 1 let me answer an interesting question, which is: What is the Ballistic Coefficient (B.C.) of an arrow? (Or at least, this arrow) I was shocked how low it is. I used the on-line ballistic calculator (web-link below) and typed in the 'point blank' muzzle velocity (394 fps), the arrow weight (433gr), and then started playing with the BC until I got the ending velocity that was close to 333 fps (actually 332fps). The BC turns out to be 0.065! This is worse than a 50-cal round-ball which is 0.068! Looking at a sleek arrow I somehow suspected that the BC might have been better than this.
