Front of Center

passthru79 · 02-18-2008, 06:13 PM

I just got done building a few maxima hunter 350's with a front of center of about 14.4%. I was just curious what everyones input is on recomended FOC, and how much difference it can make. Everyone's input is welcome.

I would be happy with 14.4%. My current arrow has 17% FOC and any new deer arrows I make will be that high or higher. I wouldn't use less than 12% for deer hunting and probably wouldn't try to get much more tha 20-22%. I also like a heavier arrow (500gr minimum total weight)with that good FOC. I know everyone doesn't like heavier arrows but I think regardless of heavy/light arrowyou need agood FOC. I think a good range is between 12-20%.

Thanks bruce. I havent had a chance to weight these but they should be right around 385 grains. I prefer to keep mine under 400 grains, just presonal preferance.

I am a huge proponent of High FOC arrows. My setup last year was a 2005 Old Glory set up shooting 65lbs with 453 grn arrows with a FOC of 22% (205 grains up front on the arrow) shooting at 260FPS with Kinetic energy of 67 ft lbs. My bow has never shot better than it does with a high FOC setup. those arrows are flying great. I highly reccomend tinkering sometime with an arrow setup with a FOC over 18 or 19 trust me you will notice a difference. Yes it will slow your arrows down and you may have to go up in spine weight but, trust me arrows with that weight up front really pack a punch. Read some of the reports by Dr. Ashby on broadheads and you will she he is also a huge propent of this also and has the scientific evidence to back it up.

14.4% is good. I am usually Happy with anything 12% or more. I built aset of FMJ's last year and ended up with over 20% but I used brass inserts to accomplish it.

Not to be a stickler but FOC is Forward Of Center. "Front Of Center" is just poor English and it makes me cringe every time I hear it. Mine has always been about 12% for my hunting arrows and a bit less for target arrows. They have always grouped fine at that FOC but I've never tried anything radical to get more and see if they get better. If I can't get the heavier shaft weight since Easton dropped the A/C Superslim I may try the A/C/C next time and use a brass insert to make up the difference to get a 500 grain arrow which is also going to up the FOC substantially.

Don't feel bad, at least you're in good company; a majority that even includes CX.

If bow and arrow are set up correctly I doubt a high FOC will help produce better groups. It is my understanding that the high FOC makes the arrow flighta little more forgiving in poor conditions and really helps with penetration. I know that, from my own experience, my 17% FOC arrows would definitely out penetrate my targets compared to arrows that I have at around 11-12% FOC. I set my deer arrows up with a high FOC for the better penetration it is supposed to provide.

I like heavy FOC too. I shoot about 12.5% on 3D and 21.7 % for hunting.
