Pretty fast!

Whoooo that's quick. I'm guessing light arrow dynamic release :).....don't keep me in too much suspense!

9.6 gpp arrow, so not light by any means.

That's all I'm gonna say (for now). :-P

Rick

All I can tell you is that that will never, EVER happen for anyone with an average (or shorter) draw length!

I’m gonna guess long arms, big hooks, and just maybe a Strike tab… Probably an unusually good string, too…..

50# Kodiak Mag drawn 29" 314 gr carbon arrow 225 fps with release.

That’s not that great I done that with my Trad Tech with Carbon Wood LONG BOW limbs 60# @ 28” 480 gr arrows average 210-215 fps all done at Lancaster Archery when Jon Werts was still there

I am going to completely agree with Corax. For those of us with a slightly shorter draw length. That aint happening. Heck, I can't hardly get to 175 with 60# bows at my draw. Spill the rest of the formula Rick. For the rest of you. No pic, no proof. :-D

-Bones

314 gr @ 50# = 6.28GPP. 480gr @ 60# = 8GPP. Rick, how much difference do you think you would gain dropping arrow weight down a couple of GGP?

Rick bought a wheel bow? Lol

Hey Bones the formula is right in front of you read it

Paul Brunner wrote in his Treestand book that his 70@26 Schafer Silvertip consistently shot over 220 fps.Not sure what the arrow weight was.

Not everything is there Gutpile. I know Rick's draw and what arrow weight he shot as to GPP, but which limbs, off what riser, and the weight at his draw. Plus, from my own tinkering, what spine arrow and what point weight. I can get an arrow tuned in different marked spines by changing length and point, and in slow motion you can see a world of difference in flight. Sure, dynamic spine they are even, and they all hit the aimed point, but speed of each and actual flight characteristics are much different.

I want to know the real details.

-Bones

A self bow with a short draw can shoot 270 with a light arrow.

The bow is 65# at my draw.

The arrows weigh 627 grains for 9.6 gpp, so no - not light weight arrows. :)

My only problem now is - the arrows are flying weak like wet noodles. Pretty sure I can solve that issue with some footing on the business end, and not have to bump up in spine. Already shooting .250s, but if I have to I'll go to .200s.

Rick

Compound

Nope, no compound, it's a recurve and somebody that knows exactly what he's doing. I've seen the latest arrow and it's interesting. Likely Rick will show it when the weather is right to get some Chrono numbers on the modified arrow.

[[[ "Compound" ]]]

Yes! That's it!

But, it's disguised as a recurve. :P :)

Rick

Lol.

“That’s not that great I done that with my Trad Tech….”

LOL….

Except that Rick’s arrow is 20% heavier on a GPP basis (AND still faster), and it’s 52% heavier than the #50 K-Mag… And comparing to a RELEASE??? ROFLMAO.

I’m looking forward to hearing more about this one, Rick!

If Rick Barbee shot a compound that Chrono would be closer to 400 FPS, most likely.. Rick, thanks for a little more info.

-Bones

Yup, and if he were shooting 8GPP it’d be probably north of 260…

Your a freaking MORON CORAX TO SAY THE LEAST aim only shooting 5# less an 8gr pp

Yes, and if you do the math, your 8 GPP is 20% less than Rick’s 9.6.

If being able to calculate a percentage makes me a moron, well, then I guess I stand convicted.

Math is hard......

Be "drooling" nice to see the ARROWS & the BOW?? I BELIEVE but shore would be nice to see the gear???

480 divided by 60 = 8 627 divided by 65 = 9.646 9.646-8 = 1.646 O.K. 1.6 is easier

20% of 8 = 1.6 9.6 - 1.6 =8 And to think I told my teacher I would never use this junk again why bother with it? :<) >>>>------> Ken

Have three bareshafts, and five broadhead arrows footed for the new string.

Now I just have a dozen more target arrows to do.

Broadhead arrows weight 649 grains, as will the target arrows.

I'm not going to foot the two fluflu small game arrows. Totally unnecessary.

Rick

Even if the chronograph is reading fast by a few fps (which it's not. I had it tested by a paint ball guy who works on them, and paint ball guns), but like I said (even if), the incremental difference in speed between the two strings is still a pretty good boost.

We'll see, but I suspect there will be some close attention being paid when I'm done with this upgrade. :-)

Rick

Ah-hah! So my suspicion that you’re running some new Skunk-works kind o’ string isn’t too far off……

Rick, pictures can be deceiving but that looks like a taper entering the shaft/footing. Doesn't that increase the chance of spittin it open. Why not remove that taper to a flat the diameter of the shaft/footing. >>>>-----> Ken

[[[ "Rick, pictures can be deceiving but that looks like a taper entering the shaft/footing. Doesn't that increase the chance of spittin it open. Why not remove that taper to a flat the diameter of the shaft/footing. >>>>-----> Ken" ]]]

Ken, those adapters are indeed campfered on the end, but the shaft goes inside them 7/16", and butts up flat.

Rick

[[[ "Ah-hah! So my suspicion that you’re running some new Skunk-works kind o’ string isn’t too far off……" ]]]

Yep. You guessed it. :-)

Old string was a hybrid 3 bundle 9 strand. 2 strands of Rhino, and 1 strand of 450+ each bundle.

The new string is a 21 strand 3 bundle 7x7x7, with the loops padded to 30. With all the silencing stuff added it still weighs 35 grains less tan the old string set up the same way.

The new string is from Bloodline Fibers, and is their Brave 99 blend, which is 100% SK99 HMPE, and is coated with some sort of VERY slick coating. Very tough to build flemish with, but I figured it out.

Even though it weighs less than the old string, it is much stronger.

Rick

Footing these arrows came very close to matching their tune to the new string. I had to raise the nocking point 1/8" from where I normally run it, which is probably due to the added FOC from the footing.

Rick

Keep in mind as you read this, that I am using a sight on the bow.

I had the sight zeroed at 15 yards with the old string.

The new string (after the arrow footing, and a 22 grain now heavier arrow) took the zero to 30 yards.

Original arrow weight 627 grains. Arrow weight after footing 649 grains. Still not quite 10 gpp, but very close at 9.984 gpp.

Yes, it's that much faster.

Rick

30 yard group before fine tuning.

Rick

30 yard group after fine tuning.

Rick

It's still to rainy, and cloudy to get good chronograph readings, but I'll do that at the first opportunity.

Now all I need to do is finish footing the rest of my arrows, and rezero my sight for 15 yards.

The bow shot very good before, but nowhere near this good, and it's quiet too. :-)

Rick

Oh, and Ken - the footing is still butted to a flat surface on the back side of the adapters.

Rick

whats your draw length?

I knew there had to be a reason. I just wanted to know what it was. Thanks, Ken

[[[ "whats your draw length?" ]]]

Just a touch over 30". I just call it 30.

Rick

Stu Miller's calculator says, that it would take an 86# conventional recurve to shoot this arrow.

Rick

3-Rivers Calculator.

Rick

With the absence of (for now) any chronograph readings, these calculators tell a pretty good tale of the results I am getting.

I don't think that footing these arrows, and bumping the weight cost me any of that 221.8 fps. If it did, it isn't much.

Anyway, that's about all the info I can share until chronographing time.

Rick

Chronograph readings as promised.

Rick

Yes it will.

Holy moly, that is swift!
