I got my new chrony in the mail yesterday and I got the following calculations with a little testing:

@ 70 lbs and 28 inch draw:

Draw Length / Draw Weight / Arrow Weight / Velocity / KE / Fletchings

28 / 70 / 425 / 270 / 68.8 /Plastic vanes
28 / 70 / 395 / 286 / 71.8 /Feathers
28 / 70 / 374 / 281 / 65.6 /Plastic vanes
28 / 70 / 345 / 292 / 65.3 /Feathers

I know that the KE is enough to blow through anything I could see in Kansas but I thought I would get your opinion anyhow. Thanks in advance.
