Ok, here's something to chew on guys.
I currently shoot a Robertson Falcon 4 recurve 53#@28" 62" bow. My arrows are as follows (please hold to remarks) Carbon express 250 cut to 29.75" with 12" of vinyl sticker wrap and four shield feathers on the back, aluminum nock adaptor and bohning t-nocks, fort he points I use 125 brass adaptor 145 steel glue-on point and 2 inches of a 2117 arrow for extra durability for a total point weight of approx. 290ish grains.
I have great foc weight and the arrows fly excellent. What bothers me is according to online calculations, my bow shoots these arrows at 155 fps (consistent) and total arrow weight being 681 grains, I get 36.34 KE foot pound of energy at impact.
I am thinking of going to the heritage 150's to see about a speed increase and thus a increase in KE if the combo works out. Is there a calculation to figure point weight or is it back to the drawing board testing different point weights until one works?
