Built two arrows. Blackeagle Carnivors 300 spine. Ctc 24 3/8. With 2 in vanes
Arrow (A). Has a total weight of 521.4 with foc of 27.27
Arrow (B) has total weight of 522.2. With weight tube. Foc of 9.85
This is as close as I can get with arrows. I cannot control dynamic flex. I also do not know how much of a factor that is. I'm sure some.
Both arrows shot from an apa m5 at 26.6 draw at 66 lbs out of a hooter shooter.
Arrows shot from 20 yards to 60 yards. Arrow (A) was high at 20 by around 1.5 inches. By 60 yards the arrow (A) was an averge of 5 inches. All groups where shot 3 times.
I could see a little wiggle in arrow (B) in flight. Arrow (A) looked like a dart. I'm sure this may have caused some flaws. But either way an arrow with same weight
I'm sure the test is flawed some. Still trying to see if I can get more of an apple to apple test
I'm going to cut the fletchings off and see if I can get a bullet hole with both shafts and retest.
At this time this is the tare at 5 ft. Not sure if this is enough difference or not. I need to talk to a traditional shooter and see if there is a better way to test this or not.
I know some of this has been tested before, but like everything you read half say one thing and the other half another. So I'm testing for myself. Plus it helps with the stressful job.
Should have spent more time paying attention in physics class. Was just to big in a hurry to get out of school.
Also has a Custom Arrow Weight & FOC Simulator/calculator

Thanks Neil. I have read this. but it's partly an opinion of the guy that wrote the artical. At least when I'm done I can answer a question about it from a testing stand point and just not from what I've read.
Either way it's fun and it gets me out of the house. But I do need input. Testing and getting an answer is not always correct. The person testing controls the outcome.
Efoc vs foc test
A good read from the Carbon Arrow University...
