Anyone Chrono thier bows?

[bigcountry]

What do you think of my speeds?  This is out of a martin savannah 50# with a FF string 29" draw  I would like to know how others with 50# recurves fair.

Savannah Longbow
590gr 2018 with 175gr tip 159fps
560gr 2018 with 145gr tip 164fps
500gr 2016 with 125gr tip 175fps

I have never been able to throw my bow that fast...  

That said...looks like at 9 gpp..you will be in the   180's.  The numbers look great, IMHO.

[beachbowhunter]

Is your bow 50# at your 29" draw?  In any case, those are very respectable numbers.

[James Wrenn]

I crono every bow I pick up.Can even tell you how fast my bowfishing bows shoot fish arrows.  :D

They are decent numbers and are simular to a large number of other bows I have shot.

[firstlightbows]

Those look about right, I cronoed a savannah  55# bow at gander mnt and it was doing around 182-185fps.  My 50# with the same arrow as doing the same speeds :0

[bigcountry]

Thanks guys.  I just wanted to know if I was there or not.

Just chrono'd my latest boo-backed osage r/d longbow today, 50lbs with 700-grain arrows ... a whopping 132 fps. But it sounds fast! Maybe God should never have created chronographs, to bust the amateur bowmaker's dreams. It's 67" now and I plan to whack it down until it shoots those heavy sticks at least 140 fps, which will meet Dr. Ashby's mins for heavy (scapula) bone-breaking. If it breaks, well, I get to build another one.

[Barney]

Never have, probably never will. Don't care how fast it shoots, just where it shoots.  

[Richie Nell]

I chronographed my Black Widow PSAX Osage 64#@29 with 605 grain arrow w/200 field point.  It shot 180 fps.  I thought that maybe a little slow.  My hunting arrow will be 810 grains with 271 up front.  I would like to think it would shoot around 160ish fps.  I am not gonna let the elk know one way or the other.

[bigcountry]

Goodness Richie, I imagine that combo should blow thru an elk fairly easy.

[stick flipper]

my ancient spirtis thunderhawk smokes an arrow. I never really cared how fast my bows were, but I noticed my arrows seemed to be flying like rockets with this bow. So I took it to a local archery store and shot thru their chrono. I averaged 179fps with a 705gr chundoo arrow. We then but my bow on the scale to see exactly what I was drawing it to. 64#@31. I shoot full length chundoo arrows and they come out a little over 31" bop. I draw to the point my BH touches the front of the shelf

[R H Clark]

I shoot a Dalaa 52 lbs at 29 in. My 376 grn arrow is 212 fps. I'll be adding a 62 grn weight tube to hunt whitetails.

Martin X-200
50# @ 28"
26.5" draw length
shooting 450 grain Grizzly Sitka's @ 167 fps

[sswv]

just did a friends Black Widow SA and it surprised us both.

53# @ 28"s
27 3/4" draw
455 grain Gold Tips
average 201 fps

[Shawn Leonard]

R-H that is less than 7gpp, no wonder it is quick. Shawn

[R H Clark]

Shawn,that is my 3D set up.I'll shoot a mid 400 grn with a 4 blade Stinger to hunt.Thoes ILF limbs can take a lot of abuse.

[LazerRay]

My BW PSA shoots a 580gr between 187 and 190fps it 54@27

[joe skipp]

Don't care how fast it shoots as long as my arrows come off clean and penetrates well. I've killed quite a few animals, pass throughs with a bow that shot 170 fps...from 25 yds and under. Hit the vitals with a well placed arrow, and HE won't know if the bow shot 200 fps or 175 fps.

[Dave2old]

A bit off-topic, but interesting nonetheless. My latest boo-backed osage r/d longbow, 50# @ 28"; 66.5" ntn, shot 700 grain maple arrows at a disappointing 132 fps. I'm trying to get Dr. Ashby's min's for heavy bone-breaking arrows, which would require, bare minimum, 700gr x 140fps. So I cut 1.5" off the bow and got it up to 55lbs ... but the speed stayed the same. On reflection, the original/66.5" bow used a fast flight string, while the cut-down 55-pounder uses a linen string (I build a lot of bows and have a couple-dozen strings-in-waiting, and use the one that's the right length for the bow.

Bottom line: In this case, ff vs. linen is worth 5 pounds of bow weight. I intend to get a ff for the shorter length to see if this bears out. Fast-flight is evolving as my One Big Exception to an otherwise purist trad bowyer. Sorry for the side trail .... dave
