I shoot a 55 @ 28 hill country harvest master. The bow is actually about 53#. I'm shooting a 620 gr gt7595 and I chronographed it at 196 fps. My draw length is about 29 or maybe 29.5, so I guess the question is, is this fast?
I'm not consumed by speed but I'm curious as the next guy. I also see a few guys once in a while mention the speed and was wondering how this stands up.
Thanks,
Adam
FWIW, I think it is fast... But again, what is fast??
I think for a trad bow especially with that heavy of an arrow that is really fast. But considering some of the wheel bows are topping 360fps these days I guess it is only relative. Put that arrow where it needs to go and speed wont matter.
I would check your chrono.....
That's awful high
thanks guys,I used two chronos one at Jim bows archery and the other at calgary archery center.
thanks again guys and yukon dave, I'll be in the yukon this fall with my brother in law trying are hardest to connect with a caribou.
For that weight of an arrow, that is excellent performance. I am not familar with a Hill Country Harvester. what is it? and can you post a picture. Thanks.
Assuming 57# at your draw, thats 11 grains per pound. 196 with fingers and an 11gpp arrow is so fast that I would think the bow scale, arrow scale, or both chronos have an issue...or its just really darn fast.
The crono at Calgary Archery center seems to be right on the button. But that is awfully fast, they have a bowscale on the wall, maybe give that a try too.
Something is not right.Draw length, arrow weight, bow weight, or the lighting for the chrono.

all trad bows are slow...that one just sounds much less slow.
That's a lot faster than anything I have. I have a 2" shorter draw, my bows are 9 pounds lighter, and my arrows weight 115 grains less.
Even 196 fps would be extremely fast for 9 gpp.
I would highly suspect the values derived.

I dont do the carbon thing,so educate me what size head are you using? and if you pull 57@29 why are you using gt7595's(full length I assume) arnt they spined to heavy for that bow? this is why I shoot wood...LOL
That's a really heavy arrow to be shooting that fast from that weight bow. If it is correct, KEEP IT!

It could be. I'm getting around 170fps with my 46 lb bow with a 550gr arrow and a 26"draw.
I'll go back to the range here in a few weeks whn I get back from Vegas. I'm spending 10 days rock climbing in red rocks. Oh and yes I also notice most people shoot the 3555s or even someone I saw shooting the 1535 on here. I think what I should do is measure the arrow weight again.
More about the arrow.
Full length 7595 traditional
100grain insert
125 gr field point
Helical is not aggressive but it's there anne I'm shooting 3 shield cuts.
I did shoot this bow as well as a caribow one after another the other day caribow was 57# @27 and I shot the same arrow and recorded 188fps for 3 shots. Later on that night after a few arrows down range I shot the harvest master again through the chrono and it recorded only 190. I personally think this is due to my form fading as the night when on.
Time between shots with each bow wasn't long I'm just not very strong
(http://i1231.photobucket.com/albums/ee508/SuperShrew/saba_0417.jpg)
that's the bow at a shoot in lethbridge alberta.
I don't own a camera so everything else is low quality.
At 11 gr per # draw weight that is faster than anything I have and I really like fast bows.

It's....DEFINITELY.....fast.
I would not want to be on the receiving end of that setup...passthroughs?...not a problem!
I shot a whitetail last year through the shoulder and out a rip. 1/4 so so slightly away from me at 22 yards. The arrow passed through so fast I second guessed and thought I shot over her back. I shot a mule deer and with a poor arrow set up lighter and shorter I didn't get the same results. I clipped a shrub with my bottom limb and at 13 yards center punched his back hip. Arrow broke the back leg bone and cut the large blood vessel back there. As he turned around I shot him through the center of te chest facing me, a desperation shot to say the least, and got about 20 inches of penetration. That being said I was shooting a lower quality broadhead and have since changed to something better.
I just ordered a Harvest Master from Roman. 48# at 29. I hope I get nice speed but more important I want to shoot it good. I went down from 52# to 48#. I think this will help me alot. Anymore pics of bow?
pdq alright!
:clapper: :clapper: That's pretty quick for sure. Sounds like one fine bow, congrats.
Don't sell it that thing it is a rocket ship. I too am wondering what is up that is very high speed for that set up.
Fast? That's smoking! I'd triple check all the numbers and if they are correct, buy a piece of that bowyers business!
I'll triple double check everything. Maybe I can convince my little brother to help me make a video of me checking this out. a run down on everything.
Might be a fun project.
britt,
Here is just about the only picture I have.
Believe me a camera is on the wish list.

****no wider than 640 please****
That is extremely fast with that heavy of an arrow.
I believe you - they look like gold Tip arrows, I see the inserts, assuming they are 100 grain inserts with 125 tip that arrow should weigh in around 520 grains or so, do you have weight tubes in them as well? or heavier tips?
Really great performance
It could very well be that fast. I watched guys testing bows on multiple chronos last year. They were claiming they were all reading slow. They were checked and the lighting was stable, so they were declared correct. Then a young fellow with a fancy takedown tried it and blew everyone's speed out of park. So one of the complainers tried his luck again and got a slow reading again. some bows are simply fast.
That's certainly faster than all my longbows. Most of mine clock out at about 155 fps.
rraming,
I'll check that out. seems like a significant difference. Would there be two types of traditional arrows from goldtip? I don't have weight tubes, but I'm going to put the arrows on a grain scale when I get back from vegas. I was at a fellow gangers house and they all came out the same but I do remember something being funny about the pink ones that I used last year and the new dozen I have for this year.
520 grains is really light though so now I'm interested to determine the error.
there is a new Byron Fergesen shaft that is alot heavier than the GT Traditionals. Really want to try those new shafts.
Right from the Howard Hill web site:
All Howard Hill longbows are laminated, with fiberglass backing for a maximum of strength and durability. These straight-end longbows give you speed, stability and cast. They are feather light in the hand and have excellent maneuverability. Our bows will generally shoot a minimum speed of 115 feet per second plus the weight of the bow (i.e. a 65# bow should shoot at least 180 fps and may exceed that minimum considering variables in bow length, draw length, and arrow weight).
520 sounds too light. I shoot a 3555 cut to 29", and with a standard insert and 175 grain head they weigh 505. Your full length stiffer arrows with brass insert must weigh considerably more.
Killdeer
GT traditional cut to 29.25" with 225 grains up front (100 insert, 125 tips)and 5" feathers 3 fletch weighs 525 grains
http://i1071.photobucket.com/albums/u512/rraming/25c263d9.jpg
I think he must have that new shaft, I have purchased maybe 4 dozen of the same shaft and they all weigh the same.

That is GT specs and weight of shafts at 29"! Killy yours at 29 weight 249.4 bare! Just trying to help here, bet your running for your scale again, sorry!
OK, doing the math, the full length GT 7595 plus 225 up front comes to 567 grains. That is still one whacker of an arrow + speed.

Totally agree!
I believe GT shafts come in two lengths, the longer being about 34". At 11.5 gr/in thats 390gr. +225 = 615 plus fletching. If thats the case, then looking at your picture looks like a 31" draw and maybe 60+ lb draw wt.
Thats the only way I can figure it.
McK
Oops, full length is 32"......There goes my theory.
When and where are you going? Is your b in law lives in the Yukon?
I'm going caribou in august if I don't draw for sheep.
Let me know, It would be fun to at least get together for a meal or so!!
I calculate 352 grs for the shaft plus 225 up front= 577 grs.12 gr nock,10 gr cap wrap,fletch 10 grs.+.That comes up to 609 grs not including glue.
If actual draw weight is 57#'s,that's 10.68 GPP.My recurves,from my chrony,shoot 180 fps with 10 gpp.My guess is,that would be about 169 fps with a 10.68 gr arrow.
Individual chronys vary and results can be affected by type of light,light angle,batter levels,and distance between screens.I read,that mobile phone transmissions,high voltage lines nearby and a host of other things can affect accuracy.One of the biggest causes of error is the distance between screens being off.I messed that up once and my bows were showing way faster than I expected they would be.Fluorescent lighting is supposed to be very bad.
It's a great looking bow and I would think very efficient with that setup,regardless what the speed is.
