I would like to hear some results with 20%+ FOC's ^^^^^^^

[ontarget7]

I have done some of my own testing to 18% but really have not had much difference from an accuracy stand point as long as my spine is in check.
I do hear from the guys that shoot 20%+ that say when you hit this mark there is a noticeable difference. Anyways I would like to hear from those that have gone the 20%+ and your findings. My goal is to improve on my 100 yard groups and get them at a consistent 5-6" and feel the higher FOC might give a slight edge when I am not doing everything perfect. The set up I will be testing will be the Spyder 30 29"/70# with Victory VAP's cut to 27" raw shaft, 125gr tip, 92 gr SS insert and 2" Blazers. This should put me a touch over 20% FOC.

Thanks Shane

Another option is the GT Velocity 300's with 100 gr tip and 100 grain brass insert. This would keep me away from an outsert which I don't care for and give me the ability to shoot any of your standard broaheads.

 

[Rick Leathley]

Sorry Shane I do not have any experience with that high of FOC. But I am interested in what you find out.

 

[Lukem]

I've been in that same frame of mind this spring. Not sure if I'll get to 20%, but I'll be up there close. I have some GT 340s that I'll be shooting out of my 60# Answer. I have some 10, 20 and 50 grain weights that I'll add up front. Haven't decided on the final setup as I'll have a little tuning to do to get the spine right. We recently moved, so hopefully I'll be able to find some time to tinker and get it figured out here soon. Keep me posted on what you do and what you figure out.

 

[ontarget7]

Just ordered some 100 gr brass inserts so I am going to go with the GT Velocity Pro 300's. If they work out it also gets me away from using an outsert which I don't really care for.

 

[Lukem]

I think that's a good choice. It seems like the outserts just give one more think to make sure is centered/aligned just right to get a broadhead to spin true. I know they're just like an insert, but it seems to me that the potential for error in that way is greater. Maybe not.

Just got in the 100 gr GT brass inserts.

I'm running brass inserts in my 200 Kinetic's.... nasty combo for sure!

Just got in the 100 gr GT brass inserts.

7, what combo of bow poundage and arrow length are u runnin to be able to get the 300's to spine correctly with about 200 grains on the nose

Bow and arrow specs are Spyder 30 70/29 with GT Velocity Pro 300's cut to 27" raw shaft, 100 gr brass inserts, 100 gr tips, 2" Blazers and acculite GT nocks. Arrow speeds are coming in at a consistent 289 fps.

High FOC does not always mean better accuracy. It is very dependent on total bow set up coupled with the right missile.

I can tell you that most pros shoot about 140 to 150 grains total up front on their target set ups. They get much less dispersion with their poor shots when and if they have them and better forgiveness.

There is a point of diminishing returns though. I think 20% is far to high for hunting. I don't think I would personally go more than about 14%. I think your long range accuracy suffers due to the heavy front end unless every arrow is shot exactly the same. Shot dispersion at the longer yardage a will grow significantly and will not be as forgiving.

This is compounds only though..

I will agree that spine selection and bow set up are the 2 most important factors that should not be overlooked. However, I have had some really accurate set ups that varied in FOC, ranging from 12-18% and one of the most forgiving ones, was a 17% set up that was shooting 294 fps. The set up I am going to test is coming in at 289 fps so I should still be able to get the 100 yard range that I like to practice at. If my accuracy in my long range shooting suffers then I will go back to some of my other options that have done well with.

Appreciate your feedback
Thanks

I'm shooting a kinetic 300. 50 grain brass insert and 125 grain head. Out of a 70 lb bow. Shoots good. FOC held in accuracy but there is a point when you can have too much I think

 

[J-Daddy]

I'm gonna play with some of the Black Eagle Rampage shafts "same size as an Easton Axis" with 50gr brass inserts & 125gr heads, X-Nock on the back and a 4" wrap with 3 Blazer vanes....Length is yet to be determined on them cause I gotta see what I can cut them down to...But I'll get them as short as I can and not be to short.
I've shot 50gr insert weights in GT Velocity 300's with a 100gr head in the past and they shot really well for me at long range...I think the added weight up front at long range & in the wind makes the arrow a little more forgiving honestly, doesn't seem like the wind pushes the arrow as much with the added FOC.

 

[cmeier117]

I didn't know the Kinetics had a brass insert option? Are you guys using some Easton ones or something?

 

[mtbshark]

I shoot BE rampage with a 50g brass HIT insert with a 100g head and i am just under 15%. I have tried a few arrows with the entire 75g insert but found that my groups where opening back up.

Yea using a brass HIT insert

 

[squeekieslayer]

All I know..... you get to shooting true consistent 5 inch groups at 100 yards you'll never have to purchase archery equipment again. You will be shooting better than the guys winning national/world field tournaments. And you'll be doing it with a hunting bow.

If 20% foc gives you that..... sign me up.

JD - what's your finished arrow weight set up like that?

 

[Stinky Coyote]

I'm heading down this path this year also, maybe not over 20% but close and just offer another shaft option to play with that will get u over 20% easier...speedpro 6.2....they weigh actual 6.25 gpi and stiff. I cut mine to 28", put some ff sk300 vanes out back with 50 gr brass inserts and 125 gr tips and on the calculators I get over 19% foc using Easton microlite nocks and over 17% with nockturnals...and my experience is my actual foc is a point higher than the calculators. Vanes r 6.8 g each so there r lighter options there without going more up front to push over 20% foc. I haven't been able to try my set up at distance yet but I had my bowtech specialist tuned up by my shop and they took six of my arrows with nockturnals at total weight 389gr and ran a 3/4" ctc group at 20 yards thru the hooter shooter which was best or second best they had seen out of the gate, twisting some nocks on same 6 arrows the got it down to 1/2" ctc for 6 shot group at 20. I know I can't shoot that well but nice to know the gear can and I built a good arrow for my 70lb bow at 29" draw. A 1/2" ctc group at 20 translates into a 2" group at 80 and even without nock tuning the 3/4" translates into 3" at 80....we will see over the summer. That's all I have for now. This is all thru a bisquit to boot, and I get 304 fps out of the set up...which was my goal, great speed, enough arrow weight, and crazy foc. So far I gotta say the speedpro 6.2's r a serious shaft contender for those looking for insane foc builds...if u get 200 gr up front instead of the 175 I have by just going 100gr inserts with 100gr tips, u will get well over 20 maybe up to 25% and still run around 400 gr keeping speeds up. Expensive tho....but doesn't seem to be as much of a factor here at rokslide...where us gear junkie whores r lurking everywhere.
