This is my first year bowhunting and before I get arrows I’ve been using weight, FOC, and speed calculators but I can’t get results that I like. I will be shooting 55 pounds with a 27 inch draw and I want around a 15% FOC arrow that’s at least 410 grains with a 125 grain fixed blade broad head and I want 270+ fps. The problem that I keep running into is that I could get a 438 grain arrow with 14% FOC but according to the calculator I will only get 242 fps and to get my desired speed I have to get the weight below 400 grains. Does anyone have a solution? Thanks in advance.
