This is probably getting to nitpicky but this is the first time that I have messed with the EFOC thing. I've got my arrow and bow tuned perfectly with 250 grn Field points. My qestion is after modifying the grizzly el grande 150+100 grain insert to the sharper bevel angle will I lose enough weight to affect flight?
use a 160gr
I lost 10 to 15 gr from my 190s after sharpening!!
I found that the metal lost by sharpening is 10-15 gns as stated above; you won't notice any difference using a fletched arrow.
I would say 5-10 grains unless you get real wild with the file.
