Honestly GFY 12% Isn't that much FOC If your looking to up It some. The experts say once you hit 19% FOC Is when you'll start seeing a difference In what FOC will do for your set up.
So in your opinion going from 9% to 12% is negligible? I'm pretty sure I'm not getting to 19% unless I start re-thinking EVERYTHING.
In my opinion going from 9 to 12 percent won't do much If any at all. I just started learning and experimenting with this stuff this last year. In previous years my FOC was a low 8% with my 2216 Eastons with a 125 grain Snuffer (total arrow weight of 560 grains). I then beefed up the tip weight on my 2216's another 70 grains or so and tried that out. My FOC went up to 12% and the penetration In my targets wasn't much more at all If any. I no longer shoot this arrow set up although It never did me wrong. I just wanted more FOC so I went In another direction with arrows and went the FMJ route. So far I'm loving them. My new set up Is at 17% FOC. It's not where I want It yet but It's a work In process.
I think that's great for just starting out fooling around with adjusting things. I like a minimum of 12% FOC for hunting. Once you get deeper into this you may want to, as others suggested, start looking bigger changes concerning FOC and total arrow weight/grains per pound. You will get told (a lot!) that you don't need extreme FOC or real heavy arrows to kill deer, and you don't, but you will learn a heckuva a lot by making those setups and those setups will be extremely forgiving. You don't really need a 60# compound bow to kill deer but the guys telling you you don't need extreme FOC or heavy arrows all use 60#+ bows .
Good advice. Just remember it's not a "choice" thing.......UNLESS you're willing to re-tune. It's not a good idea to just say...."Hey....I think I'll change my tip weight from 100gr to 150gr.". There's more to it, than that. In bow tuning.....there always comes a point of diminishing returns (ex - adding weight to the tip).
My situation is, I have a box of all my new stuff....rest, stabilizer, quiver, site.....so when I go get my new sweet baby out of layaway, I'll walk it to the archery shop, hand them all the stuff and tell them to set it up with my new stuff and shooting the new wiehted arrows....I'm dropping to 57 lbs....and would like to boost my ke. SB
I hope you have new arrows in that box. Dropping draw weight and adding tip weight (and keeping the same arrow.....spine/length) won't work.
Actually, I got two packs of 250 maxima hunters that I'll hand them with all the stuff....(they had them reduced to 49 bucks for 6, so I grabbed the two they had) The only thing left over from my original bow is my release. I'm going to have to get them to help me w/ the length to cut them... my old rig shot 28" arrows.... I'm starting over. SB
" 12% Isn't that much FOC If your looking to up It some. The experts say once you hit 19% FOC Is when you'll start seeing a difference " From the studies Ive read it would appear that the Penetration from a 12% FOC to roughly 19% Foc to 20% FOC = A Two Fold Increase in Penetration. I was previously shooting Bowtech Equalizer Compound Bow, 100 grain heads, 26.5 inch Aramid KV 250 with 3 inch Vanetec Vanes, 25.5 inch draw at 60lbs..... I just today setup for me New Carbon Express Aramid KV 250, 26.5 inch Arrow with a 100 grain Insert and 145 grain Field Point with a 3 inch Parabolic RHelical Feather, 25.5 inch draw at 60lbs..........The results in Tuning the new Extreme FOC Arrow was a perfect tune even through paper and the penetration gain is roughly 2.5 inch gain at 20 yards with the Extreme FOC arrow... flight was impressive and forgiving... and an added benefit was a quieter bow. I will be reducing the feather length to 2 inch feathers for further testing. I recently had the pleasue to attend a seminar given by Dr Ashby on the subject of Extreme FOC Arrows...... and it was Very Inlightning to say the least. and it got me playing with some new arrow setups. And I will be testing different FOC amounts for penetration results since a friend is willing to provide me a few fresh whitetail Scapulas with leg bone and tissue attached that have been kept in the freezer ,and I will be testing single bevel broadheads on the bone hits. And This Is Just Starting To Get Fun
Good post LF!! I agree, It's starting to get fun with me finding that set up trying to get to that 20% FOC. I've learned a ton and man am I Impressed with my arrow flight!! Looking forward to your results.
So....you went up 145gr in tip weight....and you're tuned? How was your tuning, before? I don't want people to get the idea that they can just add a lot of tip weight.....and expect everything to be hunky-dory. It doesn't work that way.
Jeff, The way I am approaching it is to first get my FOC where I want it and then tune. It seems the most logical way to do it from my perspective. I plan on using DW, arrow length and moving the rest a little to adjust my variables (assuming my spine is correct). I agree (unless you are damn lucky) that you can't alone just increase your FOC and expect that will be your tuning variable.
" How was your tuning, before? " The arrow was shooting extremely well ,bare shaft shooting a perfect bullet hole through paper, before I added the 100 grain insert and 145 grain field point. Now that is not to say that I wont be playing with some different shafts in the future when I attempt an even higher FOC Arrow. " I don't want people to get the idea that they can just add a lot of tip weight.....and expect everything to be hunky-dory. It doesn't work that way. " I believe Its a Spine thing, but so far I havent reached that threshold requiring me to change the spine of the shaft ... yet
