Alright EFOC fans (I am one).
A question :confused: ?
Would better performance be obtained by using a 300 grain broad head - or - by adding a 100 grain insert to the arrow and using a 200 grain broad head? Same overall arrow weight,
In theory, it should be a wash, but in actuality....?
Any advice or personal experiences? :coffee:

There would be just a tad more FOC with the heavier head/point. Not enough difference to make a difference though.
I have found an added benefit to the 100gr brass insert. It acts like an internal footing and I don't break near as many arrows on hard impacts.

As Bisch said, the heavy insert works as a footing, and really toughens up the end of the arrow. The difference in FOC using the heavy insert as apposed to a heavier head will be minimal.
What percentage FOC determines:
Normal (FOC) ?
High (HFOC) ?
Extreme (EFOC) ?
Ultra Extreme (UEFOC) ?
I'm curious as to what others get, because I have 250gr up front, and still only have 20% FOC.

My current set up is 27% FOC. 605 grain arrows that fly like darts in 57-62 # set ups (at my draw length).
Main reason for asking is that I want to try some lighter broad head types than my current heavy weights.

I will be willing to bet if you stick a 100gr insert in one of your shafts with a 100gr lighter point/broadhead, then take one of both arrows and shoot them, you will not be able to tell any difference.

Howdy Bob! Check out this little video I made a few years ago: adapter comparison. (http://youtu.be/tuGXW9KYd-E)
I've revamped my whole arrow setup a few times since then, but I haven't wavered on the 125 grain brass adapters being the best option for integrity.
I use 200 grain heads on that adapter on my light bows. It's nice to have so many head options in that grain weight. 200 Super Ace Express is my favorite for turkeys and small game around the farm! Some nice single bevel options in that range too!

I will give you an example of where going to the 300 grain head could make a difference...take a look at the VPA Penetrator broadheads and notice the 300 grain one that is .125 thick...you are simply not going to find a 200 grain head that thick...only an example though since I would not have any use for that broadhead on this continent

rbcorbitt,the further in front of the shaft the weight is,the more influence it has on FOC.The further back from the front end of the shaft,the less influence.
When you are wondering about situations like this,it's easy to test without changing your arrow.Just get some lead or solder and scotch tape it to your broadhead or behind your insert and check your balance point.You can then see exactly how much difference there is and decide if it will matter to your setup.
I keep tungsten putty on hand and it's even easier to use as I can just stick it anywhere on the arrow I want and can reuse it.

Okay, guys. Just ordered some 100 grain inserts from Big Jim's. Ordered some white cock feathers to help distinguish these arrows from my standard insert arrows.
Will play around some with the 200 grainers that I used to shoot before moving up in total arrow weight :thumbsup: !
I can imagine that a Simmons Treeshark will do a number on raccoons!

If footing your shaft, I woud prefer the heavier BH.
If not, I prefer the 100 grain or custom made 150 gn inserts with the lighter broadhead.

Thom, I also like the insert/adapter combos. Best way to strengthen integrity that I have found so far.....However not as good as what will be coming to the market very soon.
