Which Type of Arrows?
I am still a little new to bow hunting and I am wondering about which type of arrows to use with my bow. I have a 27" draw 60# Legacy, I currently have Beman 400's with 100gr tips. Just making sure these are the right type to be shooting for my setup. What does the numbers mean on the arrows? Difference between carbon and aluminum #'s. Any help here would be great, These forums have already helped me out a lot, now I cant stop coming back for more.

RE: Which Type of Arrows?
400 spine means the shaft has a spine deflection of .400
deflection is measured by hanging a 1.94 pound weight from the center of a 29 inch arrow shaft. The shaft is supported at each end 28 inches apart.
So there is a support 1/2 inch in from each end and a 1.94 pound weight set at 14.5 inches (center).
If it is labled as 5575 means 55 to 75 pond draw weight or a 7595 would be 75 pounds to 95 pound draw weight.
Yes those are the correct spine for you.

RE: Which Type of Arrows?
With aluminum arrows, the first two numbers are the arrow's diameter in 1/64th of an inch. The second two numbers are the arrow's wall thickness in thousandths of an inch. So, a 2216 is 22/64" in diameter and has a wall thickness of .016". A 2512 is 25/64" diameter and has a wall thickness of .012".
The numbers do not directly correlate to the shaft's spine. You must go to the Easton chart to figure out what shaft to use. Having said that, there are a few rules of thumb to know: The larger diameter the shaft, the stiffer it is. The greater the wall thickness, the heavier, slower and more durable the shaft is. Of course, the flip side to that is the smaller the diameter, the less stiff. The thinner the wall thickness, the lighter and faster, but more fragile the shaft is.
