Can there be to much front of center? I have 30%. NM Shelton 66" 57#@@* I pull 27= 54#. GT traditionals 29" with 175 up front.
Nope.
How did you calculate foc, that sounds high for 175gr point.
This is an easy way. http://tradgang.com/noncgi/ultimatebb.php?ubb=get_topic;f=2;t=000089
Agree with Katman, put 300gr on front and I can see it...
I like 28%-30% myself
I think the too much would be if total shaft weight is causing too much drop in your trajectory for your liking
I agree with both of the above posts. I can't see any way you can be at 30%, even with 100gr inserts???
I just ran some of your numbers thru the Stu Miller calculator, and the highest i could come up with fir that arrow was 23.1% FOC.
Bisch
I used the total length end to end 29.750. balance point 9.750.
I just watched this video and came up with 17.2% https://www.youtube.com/watch?v=BZ6U9gYI5bc
I was doing it wrong
That sounds better.
As per your question I agree with TexasKing, if overall weight gets to high for you to accurately shoot then its to high.
It's a whole new world of wonderful things when you get up around 30% foc.
Not always easy to get there but great when you do. Almost don't even need feathers with broadheads. I'm not say don't use feathers but don't really need anymore...lol
Agree with LB hntr 100%.
Your own results will not require further outside justification.
Rooted self confidence will be on the rise as that is what you will face when drawing down on your quarry.
If they are shooting well for ya???? who cares about the number! darn the torpedoes full draw ahead!
Trad Gang has a dedicated forum, which within the lauded studies, specifically and intimately address FOC.
Yes...there are many that both substantially and justifiably do care...
There is always a nesting of one desire in another, or, to shift the metaphor, always an opening toward newer horizons for the will.
I personally think that if a setup is shooting good for you , don't over think it . Don't need to know the math , that kind of thing can make you nuts if it don't fit the chart .
I don't know if this will fit the post or not but just a thought on FOC: I used to make Native American style self bows and try and use them with arrows made per copies of museum collections. One thing that seemed to be true is that these folks, who did this for a living, prefered to have a LOT of weight in front of the bow. The arrows were often 33-36" long with the draw lengths assummed to be shorter than our modern lengths. Native peoples were often drawing to a 'floating' anchor point and not drawing back to the face as we do. This is how I shot for many years with a pinch style draw. (perfect for creating target panic for me when I tried to go back to my traditional bows years later!). The arrows were made with the larger diameter toward the point and this was often around 3/8" or so with the arrow tapered back toward the nock. Sometimes they were 'compound' style arrows with the front section being of hard wood and the rest of the shaft a light wood or reed. At any rate, with up to about a 1/3 of the arrow plus stone/bone point staying in front of the bow they got plenty of mass up front. (I also believe they used overspined arrows because they would be consistent. They would always shoot a bit left, but equally, were as a weak arrow could shoot more right depending on how much more weak it was...so it might have been a variable they could control- just my theory). Anyway, these arrows would fly a lot better than ones that were shorter.
