I did some testing this summer with three groups of arrows. The goal was to just build three sets of arrows that a;; had the same end weight using 100, 125, and 150 grain fixed blade broadheads. While doing so I noticed the trend had swung from one end to the other since i had last been hardcore into bow hunting. I took a couple years off. Full disclosure I think any end of the spectrum is kind of a waste, and i also know you can get the job done with a stick and string shooting a stick with a small light rock on it so there is that.
But i am annoyed when people make unfair comparisons and declare a "winner' so here we are.
I used 3 fletch on the FMJs in the tests but switched to a four fletch i made and the result was the exact same. I have also witnessed the opposite of my findings in an uneven bag medium so there is that. All arrows were 5mm shot from the same bow. At the same distance. The FMJs had 125g heads. The blue wrapped white fletch axis had 75g ss inserts and 100 grain heads. In an even foam medium "normal" increases in FOC, or point weight if you will are not enough to overcome the friction reduction advantage the FMJ enjoys.
I really thing claiming one metric like FOC is the be all end all is silly. You can overcome disadvantage by compensating in another metric. Balance i think is key.
These tests do not "prove" anything other than in this comparison at the same overall weight in this medium that an arrow with a lower gpi and 175 grains up front did not dig as deep as a heavier gpi arrow with 125g up front. A significant FOC difference. Could you wax up the axis and get it close? Perhaps. But you could also wax up the fmj.
