I was shooting 523 grains with 20% FOC. Complete pass through on deer was not a problem. Did not get a complete pass through on hogs. Going to experiment with 650 grains and 23% FOC.

The total arrow weight will be the same but the FOC will always be a little higher. If I had the choice a 175 grain head with a 25 grain insert or a 125 grain head with 75 grains of insert weight the former gets the nod every time. It’s a little different situation is somebody is already running a certain weight head they like in 100 or 125 but for a new build the best practice is building it at the tip.

The post may be dead, so I may be wasting my time.
I have been a big advocate of the Ashby setups for years. But I started getting into the physics of archery, and I no longer preach ashby.
I do still look at some of what he did.
First, we look at what you have now. Does it work? Yes, then why change. No real benefit. Does it not work? Why not? Is it the broadhead or arrow weight? Broadhead should always be looked at first. Weight is last.?
FOC is first about flight. You need to make sure you have enough to control the arrow. I recommend 15% min if shooting fixed broadheads. Does it hurt to have more? No, but over 25%, you can start to see arrow stabilization go bad. It would help if you learned to control rear drag when this happens. most people won't see this as they very seldom build higher than 25%
FOC for penetration. There is no proof that FOC improves penetration on a compound bow shooting correct spine. No testing has been done up to this date.
Building your arrows is always fun. It allows you to learn about dynamic reactions. When you learn dynamic reaction, tuning becomes easier.

Again, would you rather be hit by a ping pong ball or a golf ball that started out at 75mph and you were 20 yards away? Or how about this, you stand 20 yards away and let me throw either one at you as hard as I can. It's likely the ping pong ball won't even reach you but I'll nail you with the golf ball. Speed does not kill, momentum kills
Closer would be same pitcher throwing an 11” softball or a 12” softball… speed difference is minimum but measurable. Ke and momentum are measurable in a math equation but that’s about it
Shoot what flys best and fits your requirements

… you missed it
Most are so passionate there is only one way, they don’t see the value to balance
I dodnt use a 11” vs 12” to compare length…. It’s a weight difference that IS MEASURABLE…..but difference in performance isn’t overwhelming
Go stand at 60….70 yards and take shots from a 700gr vs a 300gr arrow… I don’t recommended either, but reality is I wouldn’t have to achieve 3” penetration to have lethal effects. And the “ping pong ball” arrow while on paper is not as effective…. Dead is dead
