Arrow Speed

[ckhanna]

Well I shot into a chronograph yesterday and was actually alittle disappointed with the outcome. I thought for sure I was shooting closer to 300fps, but found that I was shooting at 246fps. I guess I am just curious as to what everyone else is shooting at.

[TnRidge]

I don't know and don't care . My bow shoots accuratly , that's all that matters to me .

[ckhanna]

:rolleyes: That was not my question

[Fix_F16]

I had pretty much the same thing when I first clocked my bow. Sorta like ground shrinkage. I'm 5'9" so my draw length would never allow the 30" prescribed by both AMO and IBO.You gotta remember, when you buy a bow, the advertised speed is not set up for many people. I.B.O. speed rating is much faster than most archers can do. Bow weight: 70#, draw length:30", Arrow weight: 350grains (very low for hunting). And we're assuming all the bow companies are not fluffing their stats because that's what sells bows.

If you're short like me, it's probably in the upper 200s at best.

[Chuck]

Im in the 262-265 range pulling 68 lbs with a 425+ grain arrow(if I remember right) out of a 03 Hoyt Mt Sport with 8 3/4" of brace height :). My draw length is around 30"s though.

I wouldnt want to get any faster than that.

Give us some more details about your setup.

[ckhanna]

I have a Fred Bear Code, with a 29" Draw, 75lb Pull, and we just weighed the arrows on a gram scale and for the life of me I can't remember the exact weight, but they are Carbon Express Terminators with 100g field tips. I have pictures in my profile.

[slowpoke]

240FPS at 50# pull, 29" draw with my hunting arrows and a 100g tip. My son just got a new PSE and he is shooting 315 FPS with his hunting arrows. WOW is all I got to say about that bow. We just went to ED"S archery and shot there 3D course. One pin is all he needs out to 40 yds. He is shooting 65lbs and 29" draw. At $799 for the new PSE, I'll keep my old bow. It's shoots better then I do. Some day.

[Chuck]

Depending on your arrow weight, the crono you checked your speed on might be off too. Are you shooting the 4560's or the 6075? Which arrow are yu using the hunter or regular? Arrow weight is any where from 9.5 to 12 grains per inch depending on which your using. What is the length of your arrow? Is your bow tuned properly? This does make a diference in arrow speed.

I dont know enough about your bow to say if thats slow for it. But it seems you should be faster than that.

Maybe someone else has a better insight.

I have pictures in my profile. That sounds very slow for a 75 lb bow and 29 inch draw. I would get those arrows at 375 grains and re check it IF you are disappointed with it now. Back to the question, 345 fps with pse 70 lbs 29 inch draw and 318 with bow tech at 58 lbs 29 inch. Have killed lots of deer at 26o though.:confused:

I use the same arrows at 28.5"(29" DL) and they weigh in at 455gr.;) I'm just a tad faster than you though-290fps!!:evil:

[sbooy42]

my is bow ibo is 312
I shoot 70# 29# 360 gr arrow. Last time I checked I was getting around 288-290 fps. l have added a new string and a few other things, but I don't think it should have changed much.

[kingfishcam]

70 lbs, 28 draw, 403 grain arrow between 280 and 285.

[ckhanna]

See, that is what I am looking for. Now I am going to have to do some more digging and see if something is out of tune. I am thinking that when we weighed them they were are 430 grains. I thought for sure I should have been shooting alot faster. That means a trip to the Archery Shop tonight for me!! Thanks Guy's

[Swamp Monster]

Are you sure it's 75#'s? Is it an 80# bow or just a 70# bow that is bottomed out? (maxed)'
What do you have on the string? Extra knocks? Loop? Silencers? Peep? Peep with a tube? All these things can and do kill speed more often than not. Is the draw a true 29". Some bows once set for a draw length pull a little long or a little short. Being short just half inch can slow the bow 5+ fps. Twists in the string? Nothing will kill speed faster than a poor tune.
Your also shooting heavy (by todays standards) arrows. They are good arrows though and being heavy is not a negative in my eyes anyway.

Lastly, rarely trust a chrono! It may be off a bit, or the lighting may have not been ideal etc. Chrono's can be notorious liers!

My guess that rig should be somewhere in the 260+ range. With those heavy arrows, pushing 300 is not likely with that bow.

[ckhanna]

I will take the whole setup to someone who actually knows what they are doing tonight and I will get back with all of the fine details. I am starting to think that I am very uneducated on my own bow :dizzy:

[InTheRiver]

I wonder what Im shootin

[Joe Archer]

I shoot 29 inch xx75's with 125 grain broadheads at total weight of about 485 grains. Last I checked I was around 230 feet/sec. As far as deer hunting goes, I killed some of my biggest bucks in the 80's with a Darton SL-50 that only shot about 150 fps.
<----<<<

[boathouse]

Just checked mine the other day. 254 fps. 58lbs pull with a draw of 29". Don't remember the arrow weight exactly but it might have been 360 somthing or more with 100gr field points.

[dtg]

I'd be more concerned with how quiet the bow is rather than how fast it shoots.

[trailwart]

i shot thru the chrono at eds the other day and my reflex frowler was264fps with 30' draw at 53# pull, with peep and tube, wb rest, string shox, gold tip arrows with blazers with 125 gr, feild points 29inchs. dont know the total weight but they shoot straight and flat. the bow is the 40-50# model, so i got 53# maxed out. but for me, if it only shot 150fps, with the consistancy i have with this bow, i would still be happy.

[fishunter70]

"07" Diamond blk ice 60-70lb. It's at 72lbs now maxed out. w/b rest, tru/glo 5pin sight,quiver, gold/tip 55/75 and it's @ 304.

I think it all comes down to this. If you can't put it in the boiler room, then you can't put it in the boiler room, even if you shoot the fastest bow ever made. Just like Joe Archer stated above speed means nothing if you can't get the job done and done right.

[rcdan-o]

Trust me , This is all my gear that CKHANNA is using , a brand new F1 Chrony and scale. Speed is a humbling thing that is important to an extent. with his 3 shots last night thru my chrony (430grain arrow at 240FPS) puts his Kenitic energy at 55.01 lbs. More than sufficent for any North American Animal.

YOUR bow shoots great and is consistant. Trust your skills not the speed.

There is nothing wrong with your bow, Single cam bows rarely get out of time unless something catostrophic happens.

[Get_Outside]

I have been bow hunting for almost 40 years. Started with a recurve and thought I really hit the big time when I got my first compound Bear bow. I have been shooting the same Onida bow for the last 10 years or so. Don't care how fast it is. Guys seem to get all hung up on how fast or quiet their bows shoot when all you really need is to be just a tiny bit fast than the deers ability to react. Don't worry about it so much and enjoy your bow hunting.

Just my 2 cents.

[BONE11M]

Hoyt vulcan 29in draw 70lb 402 grain ce maximas (total weight) 300 fps on the nose.

[SalmonSlayer]

Mattews UltraMax - 65lbs draw - 28.5" draw length - 100gr field tips on a Black Max arrow. Not sure of arrow total weight or exact length. Shooting at 246fps. This is with a new string with string leeches. I'll get more precise measurements tonight...

With my old string(no leeches), same bow at 67lbs draw - 28.5" draw length - 100gr tip on a Carbon Express (27.5" length) weighed 364 grains. Shot at 274fps

with a Beaman 90/110 Hunter (27.5" length) weighed 418 grains. Shot at 260fps

Are the Black Max arrows that much heavier? And does the 2 lbs draw weight make that much difference? This is a new string so I would have thought my speed went up??? :confused: I have only shot this new string a total of 90 times ... so I have not paper tuned this new string yet...would this affect the speed?

That is smokin'. :yikes:
I shoot the Terminator Hunters and have weighed them at 500.5grains all inclusive. I have shot just one time through a chrony at 275fps. Not a forgiving bow but I shoot it well. Speed does make up a little for a poor judge of distance.

[Joe Archer]

...(430grain arrow at 240FPS) puts his Kenitic energy at 55.01 lbs. More than sufficent for any North American Animal.
....

I think some people tend to exaggerate their speeds anyway. My KE with heavy arrows calculates out to about 57 and can split a 2/6 at 20 yards. I ran some of the numbers posted here through the following site http://www.archeryhq.com/kin.htm and came up with KE calculations as high as 99!!!
I know my bow is old (1998 model) but are today's bows so effecient that we can actually see KE calculations as high as 100?
<----<<<

[454casull]

I use an SL-50 for bowfishing. I remember selling those when they came out! Back on topic..Speed does allow you to be less exacting in your range estimation (we all know that) but it also allows for a margin of error in shot placement. The added KE will be very useful come the day when you hit shoulder (oh it will happen) or have that 1/4 away shot that needs the extra mustard. But some people seem to get carried away with it to a point when accuracy becomes an after thought. If you can shoot 300+ and still be accurate go for it. If you can shot the nadds off a nat at 40 yards @ 235 then more power to ya. But don't go making changes to an otherwise stable and forgiving setup just to eelk another 10-30 fps, that is not worth the effort. My sets are in the neighborhood of 275-290 with 400/366gr arrows resectively. See the signature.

[Chuck]

I think it depends on what your hunting as far as how KE you need. Anything around 50 is fine for whitetails. Last I checked my KE it was around the 68to70 range. But I went out west to hunt Elk and wanted more KE for that.

The newer bows do put out more KE and at lower poundages becouse they are so energy effecient.

Mines not new by anymeans but it works for me and with 8 3/4 " brace height its very forgiving and smooth shooting. I dont even have a stabilzer on it

[Swamp Monster]

Mattews UltraMax - 65lbs draw - 28.5" draw length - 100gr field tips on a Black Max arrow. Not sure of arrow total weight or exact length. Shooting at 246fps. This is with a new string with string leeches. I'll get more precise measurements tonight...

This is a new string so I would have thought my speed went up??? :confused: I have only shot this new string a total of 90 times ... so I have not paper tuned this new string yet...would this affect the speed?

The Black Max are a heavy arrow. Check the specs. They should give you the grains per inch plus what the inserts and knock weigh. I bet your pushing 450-470 grains for a finished arrow weight. 2 pounds of draw will equal approx 4 fps + or -
The new strings could be a big difference as well. Thread count could be different, material could be different....even tuning could be off. I've seen a new set of strings vary by 15-20fps, especially if the strings are completely different style.

CKHANNA, you knew I could not resist commenting.

319fps with 352 gr arrow(couldn't get 350gr exactly)!! I shoot a naked string (peepless and no string leeches or brass nocks). The bow came with a birth certificate of 323 but that was slightly off after adding a loop. With my 455gr hunting arrow (I use the 6075 Selects in Black), I get a consistent 289-291 for 86#'s of KE. I shoot flat out to 28 yards before the arrow shows any drop. Gotta love them Bowtechs!!:D

There is nothing wrong with your bow, Single cam bows rarely get out of time unless something catostrophic happens.

I'll have to disagree with the last part. Single cams go out even easier than duallys due to that one loooong string. It's more suceptible to stretch. It's not as evident and not as easy to tell though.

If that bow has 75# of work put into it on the draw and only returns #55 in KE than I'd get it looked at by someone that knows that cam system very well.

Can he shoot it accurately and kill deer? Yep. You bet.
But it's not hitting on all cylinders.
If those numbers are correct I'll lay money there's something amiss there.

Are the Black Max arrows that much heavier?
Not THAT much but yeah...they are.
I shoot the 340's at 27.75" and 100 grain head and it's 430 with blazers.

And the original question...

I switched cams so I don't know. With the Vipro on my BulletX maxed at 71# and a 430 grain arrow I was at 268. Those Nitrous cams I put on are quite a bit faster and the draw cycle reflects that but I haven't run it through a chrono.

[rcdan-o]

Kelly thanks for the tip Chris and I spoke this evening and found that the string on the bow is the original and not been replaced. With this info maybe he should check into a new string and have the cables looked over too while he is at it. This guy keeps all his stuff in top notch shape and is very much a perfectionist. The new string thing I definatly overlooked....

Are you still shooting your Martin? If I remember you got a new bengal last year did'nt you? thanks for your input.

I have never shot a bowtech, but that is impressive. I have a loop on mine, and a tubed Peep (big).

My Signature,, I wanted 300 fps but just can't get there with a 28.5 DL..

[LTCracc]

Is there an equation you can use to give you a ballpark. If I have the poundage, draw legnth, and arrow weight can you figure out speed + or - 15 fps.

I had a single cam once that shot pretty well and had the same thing. Went to shoot at Wilderness in AA once and Pete Chronoed it and I was very sad, Inside of 20 minutes he made a few twists to compensate for the stretch and brought it back into spec and I gained 30 fps:yikes:

Point is...may not even need a new string. Just a few twists to make sure the bow is in spec and cam is doing what it's supposed to.

And yes....I'm shooting a Rytera (Terry and Ryan Martin=RyTera) BulletX.
It's almost the same as the Bengal but a lot more expensive:lol:

[ckhanna]

Well I am shooting in a 3D shoot tomorrow or I would go and have my string assesed. Maybe it has stretched alittle. But I do know that just about a month ago I had Jonie @ country feed and archery ( Cracker Barrel ) in Vicksburg install some new string silencers and she is one of the best in the business and she said the string was in great shape. This woman has worked bows for years and I myself probably would not second guess her opinion. Thanks again for the comments Rcdano, I dont think I am to much of a perfectionist!!! :lol:

GMan55, thanks that worked perfect.

[SalmonSlayer]

Ok,

so I paper tuned my bow this weekend...it was a little high and right with the fletchings. 2 Slight adjustments and it tears both field points and muzzy 3 blades PERFECT at 15ft. THANKS ASIAN ARCHER!!!!

I weighed my BlackMax arrows at 28.6 grams...which I calculate to be 442 grains. Does anyone have an equation for grams to grains so I can verify?

I also was hitting my Trohpy Shaker Drow Away with my left vane when shooting cock vane up...which threw the fletchings right when paper tuning. I rotated the arrow on the string to put the cock vane down...which brought the paper tune PERFECT after moving the knock point down just a tad.

Now I really should put it back on the chrono and recalculate my KE...But with the old speed measurement and 442 grain weight, I am calculating a KE of 59.41. It should go up I would think...but we'll see.

Ben

[Joe Archer]

I come up with about 15.432 grains/gram.

"07" Diamond blk ice 60-70lb. It's at 72lbs now maxed out. w/b rest, tru/glo 5pin sight,quiver, gold/tip 55/75 and it's @ 304.

I think it all comes down to this. If you can't put it in the boiler room, then you can't put it in the boiler room, even if you shoot the fastest bow ever made. Just like Joe Archer stated above speed means nothing if you can't get the job done and done right.

Really? I have never seen a Black Ice get even close to 300fps on a chrono. Mine does 264fps with a a ultra rest and easton axis arrows. Is that the factory rating or did you really clock it at 304? Thats amazing.

[Michihunter]

I personally have seen a Black Ice set up at 29.5" DL and 71#'s shoot 302 fps through a chrono with a 365 gr arrow. Considering IBO is 309-317, that's pretty darn close. And having been a Bowtech fan for quite some time I can say that they may have the most accurate listings of IBO ratings in the industry. So 304 is perfectly doable.
