Yes, at least when trying to get Ultra EFOC, the lightest gpi but stiffest is the key. But the 7.4 gpi arrows should also work well.
Just weighed them again and they are 614 gr. 420 gr. up front and 33.6% FOC.
I usually bareshaft them a tiny bit weak and fletch. Then they are perfect with 4″ nanner feathers.
I am more interested in how they fly with the feathers on than off.

I have set up some arrows for my wife shooting 40 lbs. They are GT Ultralight Entrada 500. 6.3 gpi

620ish grains (don’t remember off hand)
29″ from nock groove to cut carbon.
100 gr. brass insert
300 gr. field point
20 gr. 2117 footing
32% FOC measuring from nock to cut carbon
Flys great.
AND….I can actually add more weight before they get too weak.

It should work for you.

:shock:NO,NO,NO,NO :shock:…..Let’s be very clear. 💡 “Noone is without sin, no, not one”. I am a sinner, and forgiven, but “that” happens to be one I haven’t committed.

I heard that Tatoo, the littly guy on Fantasy Island, made that orientation choice.

Yea he finally came out of the cabinet.

That is the only way I have ever done it….12, 4 and 8 with cock feather in. I just can’t figure out if it is noon or midnight.

BTW Patrick…it is a choice, and that is only one among trillions.

I sure do think so. They have an incredibly smooth draw and very durable. I have dropped mine from 20 ft. in a tree. No issues at all.
The customer service is ridiculously good. I had mine for 1 year and saw Roger with Black Widow at a trad shoot. I had noticed two or three tiny (maybe 3 mm long) white marks under the glass on my limbs. I showed them to Roger just to see what it may be. He said that it was totally a cosmetic issue that they sometimes see with bamboo and it will never affect the bows performance. Then he said.. “What kind of limbs do you want to replace them with? Any kind. I will make them and have them to you in 8 weeks”. 7 weeks later I had new Kingwood limbs.

For really no reason at all he gave me brand new $700 limbs.
I know there was absolutely nothing wrong with my old limbs because I just finished smoking the 3d shoot.

Love the bow.

My only concern is how they’ll fly

I’ll settle that right quick like…

They are great flying but bad medicene for anything that wants to create resistence.

Shoot at least 10 grains per pound

That seems like such a common statement among us bowhunters and I agree unless you are shooting less than 60ish lbs. At 40 lbs. a 400 grain arrow is too light, IMO. At 50 lbs. a 500 gr. arrow is too light, IMO

Patrick,
You are just reinventing the yard darts. I have been trying to make a “yard dart” with my new 200 Grizzlys on the end.

in reply to: Mechanical Advantage question #21751

It is just a file I have had a while now. It works well because it does not take off more metal than I want or faster than I want. Sometimes I will use a flat file backwards so it doesn’t take off too much.

Then I use the ceramic rod to take off even less metal but just enough. After that I like to strop it using cardboard. I am not an expert in sharp metal edges but I’m telling you I can’t imagine getting anything sharper. The new factory 25 degree bevel is key.

in reply to: Mechanical Advantage question #21606

The new 200 Grizzlys are extremely easy to sharpen.
In literally 13 minutes I had both edges on one broadhead ridiculously sticky, shaving sharp. I have never gotten anything that sharp before. I lost a total of 2 grains.

I used a dull 7 inch flat file and a ceramic stick.

160 gr. steel adapters
If anyone is interested I can make more and sell for $12/doz shipped.

I will put these heads on a GT Ultralight 300. It is 827 grains and 32.9% Ultra-EFOC. Launched by my Black Widow PSAX 71@31.
I cut and pasted 50 grains and increased FOC by .6% from 32.3 to 32.9%.
I took away 50 gr. of lead from behind the insert (being closer to fulcrum) and then replaced the 50 gr. by using modified 160 gr. adapter and heavier broadhead with actual weight of 224 gr. including lead in ferrule above adapter(being farther from fulcrum).
Total weight being the same but managing the weight getting it as far front as possible maximizes FOC.

Can Ultra-EFOC really expand the range of arrow tuning?

Here’s one for ya. I hand loaded an arrow for my Black Widow recurve being 71@31. The arrow is 32 in., 830 gr., 32.3% FOC. It flys perfectly out of my bow. Saturday it was shot out of two other bows as well.

The other two Black Widow bows shot with me at the Spring Fling 3D shoot at Tannehill this past weekend. One of the bows was a SAX 49@30 and a PLIII 65@30. I shot MY arrow out of the PL. It shot absolutely perfect..a little slower… but perfect. The other guy shot MY arrow out of his SAX and he said he wanted every detail of how I built that arrow because it shot perfectly out of his bow. 70ish, 65 and 49 lbs. shot perfectly with same Ultra-FOC arrow.
I am not sure how that happened but I’m leaning toward having so much weight up front. It was really amazing to us as we watched that occur.

Let me know what you think.

Tom,

Speaking of nocks, I do cut 1/8″ or so off the male portion of the nock. It reduces the rear by 2 grains. As Dr. Ed said, every little grain counts.

Proper weight management = most efficient FOC
