Put two different arrows through the chronograph today, with two different bows. Just out of curiosity and for education's sake.
one arrow is 575gn, the other 300gn.
One bow pulls 50#, the other pulls 43#. Both drawn to 28 inches.
Here are the results
50# pyramid reflex shot a 575gn arrow at 140fps. Chatgpt (i know lol) estimates for a 10gpp arrow this would be between 148-153 fps. Not bad.
With the same bow, the 300gn arrow was shot 158 fps. I can't promise my release is consistent, but I was trying for consistency in release and draw length.
Next set of photos is a 43# rock maple bow with reflexed tips. It shot the 575 gn arrow at 127 fps. Again chatgpt estimates about the same, 150fps with a 10 gpp arrow. Not bad either.
